Previously CMake may generate incomplete transitive requirements in
CMakeFiles/<target>.dir/CXXModules.json and therefore in module mapper
for compiler, when source files were listed in CMakeList.txt in a
certain order.
This commit fixes the problem by correctly tracking unfinished
transitive requirements computation of module units.
There have been a simple circular test case whose circular dependency
was reported by build system. Now with this correct implementation it's
reported by CMake generating module mappers.
Add two test cases for transitive requirements computation, one with
adding source files in hardcoded order, and the other in randomized
order.

Since commit 337bc5662c (if(): add operators IS_READABLE, IS_WRITABLE
and IS_EXECUTABLE., 2023-10-21) we create some non-readable directories.
CMake 3.28 and below do not know how to delete them, so some nightly
builds fail ctest_empty_binary_directory. Add read permission to those
directories when we are finished with them.
Tell users what generators *do* support C++ modules. Report the current
generator to make clear it is not one of those supporting modules.
Also clarify the purpose of the existing documentation references.
Fix commit e40d2cb3af (Xcode: Add embed resources support, 2023-07-31,
v3.28.0-rc1~281^2). The implementation should not name the `_PATH`
suffix explicitly. That variant is automatically handled by
`cmGlobalXCodeGenerator::AddEmbeddedObjects`.

Previously we issued an error when the `.rpm` suffix is missing.
Instead, append the suffix automatically. This matches the behavior of
`CPACK_ARCHIVE_FILE_NAME`, to which the archive format suffix is
automatically appended. With this change, developers can simply do
set(CPACK_RPM_comp_FILE_NAME "${CPACK_ARCHIVE_comp_FILE_NAME}")
Previously we issued an error when the `.deb` or `.ipk` suffix
is missing. Instead, append the suffix `.deb` automatically.
This matches the behavior of `CPACK_ARCHIVE_FILE_NAME`, to
which the archive format suffix is automatically appended.
When a target uses objects from another target which provides modules as
sources, the modules provided by the referenced target must also be
treated as if they were provided by the referencing target. Add the
concept of "forwarding" modules so that consumers can use modules
created by these sources as well.
Note that this is only sensible for Fortran where module usages are
implicit as far as CMake's visibility model is concerned. C++ modules
have their own concept of visibility which does not require or support
such `$<TARGET_OBJECTS>` reuse in this way.
When `clang-scan-deps` fails to scan (e.g., bad source syntax, junk
flags, etc.), the redirection unconditionally updates the file. If this
fails, the `.ddi` file timestamp is updated. If the state is then
reverted (e.g., the command line returns to the state of the last
successful build), the updated file is not useful, but `ninja` does not
rerun because:
- the command hash matches the last successful run
- the output file is newer than its inputs
However, since the `.ddi` file has been updated with bogus contents from
a failed scan, collation fails as the `rules` array is empty (or
incomplete from a batch scan).
If `clang-scan-deps` were properly aware of its output file, it could
use this to not write the file if any inner scan fails. Requested in
https://github.com/llvm/llvm-project/issues/72875.
