In order to enable code relocation, we use a custom target
(code_data_relocation_target), and add files we wish to relocate, as
well as which sections should be relocated to the COMPILE_DEFINITIONS
property for the target.
This approach has been fragile, because COMPILE_DEFINITIONS can also be
added to for all targets using `add_definitions`. This means if another
part of the project uses `add_definitions` and
CONFIG_CODE_DATA_RELOCATION is on, a warning will appear about the
"file" not being found. The "file" of course, is just the definition
added by `add_definitions`.
To work around this, switch to overloading the INTERFACE_SOURCES
property. This property should be a bit more robust, because nobody else
will add sources to the code_data_relocation_target.
However, this approach has the downside that the CMake documentation
pstates targets created with `add_custom_target()` (which the
code_data_relocation_target is) do not have an INTERFACE scope for
their sources- so while this approach works, it is not officially
supported by CMake

ramfunc region is copied into RAM from FLASH region during XIP init. We
copy from the loadaddr of the region, and were previously loading to the
symbol __ramfunc_start. This is incorrect when using an MPU with
alignment requirements, as the __ramfunc_start symbol may have padding
placed before it in the region. The __ramfunc_start symbol still needs
to be aligned in order to be used by the MPU though, so define a new
symbol __ramfunc_region_start, and use that symbol when copying the
__ramfunc region from FLASH to RAM.

To use Xtensa toolchain, various environment variables must be
set so the executables can find necessary files and what core
to compile for. This becomes an annoyance when you have to
test multiple boards with different cores. You have to use
one set of environment variables per core. Twister cannot test
them all in one setting, and it is especially annoying doing
west builds. So enhance the environment variables handling so
that TOOLCHAIN_VER and XTENSA_CORE can be replaced by
TOOLCHAIN_VAR_<board> and XTENSA_CORE_<board> where <board>
is the normalized board target (think <board>.yaml). CMake
will then figure out the core ID for the toolchain to use.

xt-clang uses GNU Assembler (xt-as) based on binutils. However,
CMake doesn't recognize it when invoking through xt-clang. This
results in CMake going through all possible combinations of
command line arguments while invoking xt-clang to determine
assembler vendor. This multiple invocation of xt-clang
unnecessarily lengthens the CMake phase of build, especially
when xt-clang needs to obtain license information from remote
licensing servers. So here forces the assembler ID to be GNU to
speed things up a bit.

The build_info function provides a generic and stable way of dumping
build information to the <build>/build_info.yml file.
The build info file is in YAML format and the keys in the file are
intended to be stable, as to allow external tools to retrieve
information regarding the build.
The main differences to the CMakeCache.txt are:
- Settings in the CMakeCache.txt are user controlled, whereas the
information in the build info file is intended to be those values
which are used by the build system regardless if those are specified
by the developer or picked up automatically.
- Internal build system variables are not present in the CMake cache
and should not be, because their values are calculated when CMake
runs.
This also has the benefits of decoupling CMake variable names from
build info keys. Several CMake variables has internal build system
names, and the build system is free to rename those at its own
discretion.
Having dedicated key names ensures a stable API that external tools can
rely upon.

Newlib or Picolibc libraries for LLVM may be compiled or installed from
pre-built sources independently of LLVM itself.
This means that always indicating that TOOLCHAIN_HAS_NEWLIB=OFF and
TOOLCHAIN_HAS_PICOLIBC=OFF are wrong. But it could be just as wrong to
always indicate suport for newlib or picolibc.
Some pre-built LLVM toolchains are provided with default picolibc
support, such as LLVM for Arm embedded, but can also be used with newlib
be installing newlib add-on package.
Unfortunately it's not possible to query LLVM regarding newlib or
picolibc support.
Developers have the option of `-DTOOLCHAIN_HAS_<NEWLIB|PICOLIBC>=ON`,
but this is not widely known and cumbersome to do for each build.
An indication of newlib or picolibc support is the presence of library
specific headers, so to improve current situation we check for library
specific headers, and if those are present we assume support for the
library.
This commit improves the current support for LLVM in Zephyr when
cross-compiling, especially for users of LLVM for Arm embedded.

Zephyr is a bare metal build where standard libs are disabled.
This means that c and runtime libraries must manually be linked in.
This has generally been handled by using CMake's link libraries handling
but the issue with that is both de-duplication but also library link
order.
Standard libraries must be linked at last location to ensure symbols
are always available, however this is not optimal with
target_link_libraries() because this would ultimately require every
library to know the c library to link with, which is not desired.
Therefore, setup standard C and runtime library linking in linker
CMake files for toolchains where this is required.
This commit expands the principle introduced with toolchain abstraction,
see PR#24851.
This means that a toolchain implementation may specify standard C,
runtime, C++, etc libraries, as well as their link order.
Because a property approach is used, then Zephyr modules, such as the
Picolibc module can adjust such properties.
An optional `zephyr_linker_finalize()` macro is called at the end of
Zephyr's CMakeList process and can be used by the toolchain
implementation to define the final linker invocation.
This aligns the linker handling flow to the principle introduced in
PR#24851 and improves the flexibility and robustness of Zephyr build
system.

Currently, the linker that is used when performing various cmake checks
(check_c_compiler_flag, for example) may be different than the linker that
will be used during the actual build. This happens as we currently specify
'-fuse-ld' to force the appropriate linker a) after many such checks have
already happened and b) in a way which is not automatically propagated to
check_c_compiler_flag (and friends). As a result, the toolchain's default
linker will generally be used for such checks regardless of which linker
was selected in Zephyr.
This can lead to a number of surprises when building Zephyr, particularly
when building with clang. For example:
- If the linker is misconfigured, where the build will fail can vary
depending on whether the linker is the toolchain's default. When the
configured linker happens to be the toolchain's default, the build
(helpfully) fails quickly on the checks for a basic working toochain.
When the configured linker isn't the default, the build won't fail until
the final link steps.
- The build can fail due to issues with a linker other than the one
configured by the user in Zephyr. For example, LLVM toolchains without
lld will generally fail to build Zephyr (the checks for a basic
working toochain will fail) for targets where lld is the default in LLVM
even if GNU ld is configured in Zephyr and would otherwise be used in the
final build.
- Flags which are only added if check_c_compiler_flag (or similar) succeeds
may be unexpectedly omitted during the final build if the flag is
supported in the configured linker but is unsupported in the toolchain's
default linker (as check_c_compiler_flag will test using the default
one).
Note that this isn't limited to clang--even when we are building with
Zephyr's SDK and force ld.bfd, we seem to use the 'ld' variant during the
cmake checks (though this generally seems fairly harmless compared to
mixing ld/lld or other proprietary linkers).
To fix this, ensure the appropriate 'fuse-ld' is set early enough and in
such a way that the same linker will be used throughout the entire build.
