Add a symbol to enable GNU C Extensions. And a hidden option for
toolchains to signal GNU Extensions support.

Print the name of the discovered toolchain as well as the variable
used to initialize it.
This is nice to know when doing remote support, since users will
sometimes misconfigure their toolchain and not know what that means.

This forms the foundation for the abstraction of the binary tools,
where the following steps are taken:
- Move binary tool resolving, such as objcopy, objdump, readelf and
so forth, out of compiler definitions and place in a dedicated binary
tools folder with the binary tools supplier as subfolder, similar to
the compiler and linker directories.
- Create binary tool sets, gnu, host-gnu and llvm.
- Each toolchain selects the required set of binary tools by setting
BINTOOLS via its generic.cmake as it also does for compiler and linker.
The intent here is to abstract Zephyr's dependence on toolchains,
thus allowing for easier porting to other, perhaps commercial,
toolchains and/or usecases.
No functional change expected.

The LINKER variable is introduced to follow the same logic and flow as
the existing COMPILER variable: That is, each TOOLCHAIN is responsible
for choosing COMPILER and LINKER.
Currently, Zephyr's build system is hardcoded for GNU ld.
Reflect this in LINKER by letting all existing toolchains use GNU ld.
No functional change expected.
This is motivated by the wish to abstract Zephyr's usage of toolchains,
permitting non-intrusive porting to other (commercial) toolchains.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.
