This was previously fixed by commit d46590910c (Check*CompilerFlag: Do
not set result as a normal variable too, 2020-09-21, v3.18.3~1^2^2), but
was regressed by refactoring in commit 90dead024c (CheckCompilerFlag:
unified way to check compiler flags per language, 2020-09-25,
v3.19.0-rc1~88^2) due to the changes being developed concurrently.
Fix it again, and add a test case.

In commit a90d2a9eed (IntelLLVM: Add support for Intel LLVM-based
compilers, 2020-11-02, v3.20.0-rc1~89^2~20) we accidentally left out
activation of the C/C++ standard level selection logic when IntelLLVM is
targeting the MSVC ABI.

Express the cache entry with `option()`. In combination with policies
CMP0077 and CMP0102, this allows project code to control the switch with
a variable:
```
set(MPI_CXX_SKIP_MPICXX TRUE)
find_package(MPI COMPONENTS CXX)
```
Update the change from commit c6aaaf066a (DetermineCompiler: Restore
identification of MSVC with no INCLUDE dirs, 2021-06-29,
v3.21.0-rc2~6^2) to also work with no `LIB` dirs. Add the `-c` flag to
compile an object file without linking.
Before this a downstream code linking to `CUDA::cusparse_static` and
`CUDA::curand_static` would get a link line with `libcusparse_static.a`,
then `libculibos.a`, then `libcurand_static.a`. Use `IMPORTED_LOCATION`
to tell CMake about the proper dependency ordering where `libculibos.a`
comes last, because the other two libraries depend on `libculibos.a`.

Since commit bd844387df (ROCMClang: Add the ROCm toolkit derived clang
compiler to CMake, 2020-08-28, v3.21.0-rc1~66^2~6), our generated
compiler id source file contains a preprocessor condition of the form
#elif ... && __has_include(...)
When MSVC is invoked with no include directories in the `INCLUDE`
environment variable or in `-I` flags, its implementation of
`__has_include` errors out immediately. This breaks identification of
the compiler.
Work around the problem by adding a fallback attempt to compile the
identification source using a dummy include directory.
RPM 4.11.3 for el7 contains backported support for the RPM weak dep tags.
It only supports querying those tags, but rpmbuild can not make use of them.
Since CPack relies on rpmbuild --querytags to check for support, this
commit switches to rpm --suggests to check for support of weak
dependencies.

Follow the approach from commit 1d21dd0f7c (enable_language: Assume
compiler works if ABI detection compiles, 2020-05-25, v3.18.0-rc1~93^2)
to avoid a redundant check for F90 support. Almost all maintained
Fortran compilers support F90 these days.
Fixes: #22222
In 3aec26660a (Merge topic 'nasm_add_deps', 2021-03-03) the
ASM_NASM language enabled the generation of GCC compatible
depfiles for NASM. Unfortunatly, those are not supported by YASM.
Fixes: #22341
