Since commit c1e812ad4f (target_link_libraries: Improve tolerance of
unquoted generator expressions, 2022-02-15, v3.23.0-rc2~11^2) we
accumulate consecutive non-keyword arguments to recover an unquoted
generator expression as a single entry. When given multiple consecutive
non-genex library names, the grouping breaks our logic that expects each
entry is either a raw target name or a genex. Revise the logic to only
accumulate multiple arguments when they end inside a partial genex.
This bug caused `target_link_libraries` to stop wrapping static library
private dependencies in `$<LINK_ONLY:...>` for `INTERFACE_LINK_LIBRARIES`
when multiple consecutive library names are given. Add a test case
covering that behavior.
Fixes: #23302
Since commit 29ea94e17c (BinUtils: Avoid llvm-ar on Apple platforms,
2022-03-03, v3.21.6~1^2) we do not consider `llvm-ar` at all on Apple
platforms. However, there are existing cross-compiling use cases in
which the toolchain has `llvm-ar` but not `ar`. Prior to the
re-ordering in commit cf82300a63 (BinUtils: Clarify search logic and
make it more consistent, 2021-05-27, v3.21.0-rc1~119^2~2), we preferred
`ar` and then `llvm-ar`. Restore the original order for Apple.

Follow up commit 79f64cc773 (Help: ENVIRONMENT_MODIFICATION clarify only
supports singular values, 2022-02-23) to specifically call out the list
format.
Issue: #23315
Not all the behaviors of CMake variables for ignoring search
locations by find_...() commands were fully documented.
Add the missing effects, clarify the wording and restructure the
way the details are assembled to reduce duplication.
Also improve the cross-referencing to ensure all the related
variables are more discoverable.
Issue: #20878
Since `CMAKE_ARGS` is used to construct the default `CONFIGURE_COMMAND`
for CMake-based external projects, the `LIST_SEPARATOR` option works for
it too.
Clang does not automatically choose an architecture supported
by the SDK. The `OFF` value is meant for users to provide their
own architecture flags, so provide one as part of the test.
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.
Fixes: #23310
