538ff514b5 Link Step: use the correct linker for depfile handling
c26c6ac488 Link Step: compute effective linker used by the compiler
Acked-by: Kitware Robot <kwrobot@kitware.com>

Extract the effective linker during the computation of implicit artifacts
delivered by the compiler to the linker.
Define various variables describing the linker:
* CMAKE_<LANG>_COMPILER_LINKER
* CMAKE_<LANG>_COMPILER_LINKER_VERSION
* CMAKE_<LANG>_COMPILER_LINKER_ID
* CMAKE_<LANG>_COMPILER_LINKER_FRONTEND_VARIANT
This is complementary to feature introduced by commit 96a953b1ed
(Add options to specify linker tool, 2023-09-27).
Fixes: #17596, #18209, #25344
-fno-ansi-escape-codes is used only on Windows by Clang.
Without the flag color diagnostics are displayed only if clang.exe
is executed directly. Build tools like ninja and mingw32-make
will not display colored diagnostics.
Using -fno-ansi-escape-codes will make the build tools pass
the colored diagnostics to the calling application e.g IDE.
Fixes: #24235
Offer the capability, through variable `CMAKE_LINKER_TYPE`, as well as
the target property `LINKER_TYPE` to specify which linker must be used.
The implementation of this capability is specified by variables specific
to the language and linker type: `CMAKE_<LANG>_USING_LINKER_<TYPE>`.
Some definitions are provided as part of `CMake`.
For example, to select the `LLVM` linker rather than the standard one,
the type `LLD` should be specified through the variable `CMAKE_LINKER_TYPE`.
And, on `Apple`, `Linux` and some environments on `Windows`, the variable
`CMAKE_<LANG>_USING_LINKER_LLD` has value `-fuse-ld=lld`. And for `Windows`
environments based on `MSVC`, where the linker is used directly, the tool
`lld-link.exe` will be used rather than `link.exe`.

In commit e9eabb0dcd (ADSP: Configure compiler in compiler module,
2022-03-24, v3.24.0-rc1~331^2~1) we added compiler information modules
for the ADSP C and C++ compilers. Add one for the assembler too.
We already identify the ADSP assembler since commit f83330ed6c (ASM:
ADSP assembler identification, 2018-01-30, v3.11.0-rc1~35^2).

The compiler does not yet support everything needed to integrate well
with the MSVC ABI, in particular for runtime library selection and debug
format selection. Document them in FIXME comments and leave this
support undocumented by CMake for now.

These are printed by LLVM-based compiler drivers targeting the MSVC ABI.
In our use case for this, `CMAKE_LINKER` may not yet be known, so do
not include it in the test data.

Improves the handling of CUDA layouts where we have multiple include
and library directories listed in the output of `nvcc -v`. This
updates both when the CUDA language is enabled or not.

Update the Clang version checks added by
* commit eacacc70fc (Clang: use -std=c++23 for Clang 17.0+,
2023-05-08, v3.27.0-rc1~115^2)
* commit 0183956d30 (Clang: C++26 support,
2023-05-16, v3.27.0-rc1~85^2)
to account for Android NDK r26's distribution of a Clang based on a
development version of LLVM/Clang 17.0 that pre-dated addition of
these flags.
Follow the pattern from commit 12e6796b62 (Android: Do not pass
non-existent Clang -std flags, 2018-04-02, v3.12.0-rc1~284^2),
which fixed the same problem for `-std=c++17`.
