Kumar Gala 00c7ce7942 linker: move where we define _LINKER and _ASMLANGUAGE
Move _LINKER and _ASMLANGUAGE to target.cmake because of how we pick the
linker script that might be used.  This way regardless of how or where a
linker.ld gets included we will always set _LINKER & _ASMLANGUAGE (so
any header that needs check based on those defines they can,
specifically generated_dts_board.h)

Mark Ruvald Pedersen 4052bac93f cmake: Introduce toolchain_ld_link_elf to abstract linker invocation
Final step of linker abstraction:
 * Abstract zephyr_lnk by including it in toolchain_ld_link_elf.
 * Abstract relevant uses of target_link_libraries.
 * Introduce toolchain_ld_force_undefined_symbols.

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.

Wentong Wu 743a184b2d scripts: mpu align for ro section of new memory region on non-XIP system
on non-XIP system, SRAM is the default region, and relocated .data
section and .bss section of SRAM shouldn't be inserted between
_image_rom_start and _image_rom_end, because the memory region between
_image_rom_start and _image_rom_end will construct the mpu ro region.
Also for the newly added memory region on non-XIP system, the
relocated .text secition and .rodata section should also be mpu aligned.

Fixes: #16090.

Mark Ruvald Pedersen 5f347eefe6 cmake: move configure_linker_script to ld/target.cmake
While configure_linker_script() may be useful for other linkers, it
currently only aimed at GNU ld. To really be useful among different
linkers, we would need to abstract its usage of the C preprocessor.
We can do this later, if needed.

No functional change expected.

Mark Ruvald Pedersen 4080818300 cmake: Toolchain abstraction: move LINKERFLAGPREFIX under GNU ld
* LINKERFLAGPREFIX's value is GNU ld specific, and
* LINKERFLAGPREFIX is not a convention always honored by all linkers.

Thus we shall not set it from the common root CMakeList.txt.
So we move to linker/ld/target.cmake.
