CUDA 11.6 added the `nvcc -arch=native` flag to automatically compile
for the host GPUs' architectures. Add support for specifying this
special `native` value in `CMAKE_CUDA_ARCHITECTURES` and
`CUDA_ARCHITECTURES`. During the compiler ABI detection step,
detect the native architectures so we can pass them explicitly
when using Clang or older versions of nvcc.

They are stored in a slightly different place with oneAPI than they
used to be in PSXE.
A similar change was made for Windows by commit 956160bb9a (IRSL: Fix
search for Windows redist files with Intel Classic compiler, 2021-09-23,
v3.22.0-rc1~88^2), which left a comment about the locations relative to
the Classic and oneAPI compilers.

Since commit cf82300a63 (BinUtils: Clarify search logic and make it more
consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we correctly prefer the
more-specific name `llvm-mt` over `mt` when using Clang. However, the
`llvm-mt` tool does not yet support all the flags we need in the
implementation of `vs_link_{exe,dll}`. Prefer plain `mt` for now.

The change in commit cc4da8d13a (IAR/CXX: Fix compatibility with CMP0057
OLD, 2022-01-29, v3.23.0-rc1~46^2) broke the detection of C++ version
because the `IN_LIST` operator cannot work directly on a list but
requires a variable.
Fix logic added by commit 7fdd5128b1 (FindMatlab: Fix version selection
if a version is given, 2021-07-02, v3.22.0-rc1~66^2). Ensure that
`_list_index` is always initialized to -1, akin to `list(FIND)` not
finding a match.

Since commit cf82300a63 (BinUtils: Clarify search logic and make it more
consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we correctly prefer the
more-specific name `llvm-ar` over `ar` when using Clang. However, on
Apple platforms, `llvm-ar` does not generate a symbol table that the
Apple linker accepts. Fall back to `ar` on Apple platforms.

Skip the architecture verification check for these values on Visual
Studio. It cannot be implemented correctly until future work delays the
check to the main compiler test step.
Issue: #23164, #23161
Changes in commit 8f64df0a7c (CUDA: Generic all and all-major support,
2021-12-19, v3.23.0-rc1~23^2) broke our architecture verification checks
when using `-arch={all,all-major}` with NVCC 11.5+. If we test the
compiler with `-arch={all,all-major}`, we have no expected list of
architectures, so skip the check.

Refactor the logic checking `CMAKE_CUDA_ARCHITECTURES` special values.
Switch on the value first, and then make other decisions for each case.
This makes room for other special values to be added later.
Revert commit 5efb6fb516 (FindThreads: Honor THREADS_PREFER_PTHREAD_FLAG
when pthread is found in libc, 2021-11-03, v3.21.5~4^2). The check for
the `-pthread` flag can pass on compilers like XL, that interprets it as
`-p -t hread` and returns zero. Prior to that commit, we did not use
the check in the `CMAKE_HAVE_LIBC_PTHREAD` code path. Now we do, it
succeeds, and we incorrectly add the `-pthread` flag for XL.
This change was backported to the 3.21 and 3.22 release series long
after they initially came out. Since there may be more cases where we
now add `-pthread` incorrectly, it is simplest to revert the change in
all release series pending further investigation.

Fixes build project error because the OS directory was a relative
path from the binary directory.
Fixes issue during project regeneration where the `-os_dir` project option
was missing because GHS_OS_DIR was not properly stored in the cache
file.
This error was introduced by commit aa59eaac4f (GHS: Allow setting GHS
variables from toolchain file, 2021-11-15, v3.23.0-rc1~337^2).
