C++ module support puts the export name in a filename. Export names with
`:` in them are not valid filenames on Windows. Add a method to escape
names as necessary.
See: #25828
Since libuv commit `83efa3dd71` (Reland "macos: use posix_spawn instead
of fork", 2022-03-02, v1.44.0~10), `uv_spawn` on macOS < 10.8
has been observed to cause kernel panics and/or resource exhaustion.
This became particularly noticeable in CMake since commit 5420639a8d
(cmExecuteProcessCommand: Replace cmsysProcess with cmUVProcessChain,
2023-06-01, v3.28.0-rc1~138^2~8). Prefer `fork` over `posix_spawn` in
libuv when targeting macOS < 10.8.

We place the same target ordering dependencies on either the
`_autogen_timestamp_deps` target or the `_autogen` target.
Refactor the logic to avoid duplicating that code.
In commit aebfbcaa46 (AutoGen: Use depfiles for the XXX_autogen ninja
targets, 2020-01-14, v3.17.0-rc1~58^2) the `_autogen_timestamp_deps`
target was given target ordering dependencies through its custom command
rather than direct target dependencies as on the `_autogen` target.
Then commit 895fa3433f (cmQtAutoGenInitializer: support IMPLIB-only
imported targets, 2021-09-23, v3.22.0-rc1~80^2) converted some
target-level dependencies into file-level dependencies on the custom
command. This only works with a monolithic build graph like Ninja.
Since commit ebc9e448b3 (Autogen: Add depfile support for Makefiles,
2023-09-07, v3.28.0-rc1~101^2~1) we use the `_autogen_timestamp_deps`
target in Makefile generators too. This exposed the missing target
ordering dependency.
Fixes: #25766
Xcode passes a new `-use-frontend-parseable-output` flag to Swift that
conflicts with our `-parseable-output` flag. Use a different flag for
the test case.
Since commit 6a3059e66f (FindTIFF: bridge `tiff-config` into
FindTIFF-compatible interface, 2023-09-14, v3.28.0-rc1~87^2)
we try to find the upstream TIFF cmake package. However, it
is called `TiffConfig.cmake`, not `tiff-config.cmake`, so we
need to match the capitalization of the package name.

This was broken by commit df08c37a42 (cmGlobalGenerator: Add unity/pch
sources after computing compile features, 2024-02-02, v3.28.3~1^2~1^2),
and 3.28.2's commit 76b5383123 (cmGlobalGenerator: add unity sources
after computing target compile features, 2024-01-01, v3.28.2~17^2~1).
The problem is very similar to that fixed by commit 4e8f24e977 (PCH:
Clear link interface cache when adding PCH object to it, 2022-01-24,
v3.23.0-rc1~44^2~9). Generalize that fix.
Fixes: #25696
When cross-compiling, `clang-scan-deps` needs help to find the correct
location of core headers such as `stddef.h`. Always determine this path
and pass it when available.
Fixes: #25590
This allows for transitive modules to work because
`$<COMPILE_ONLY>`-wrapped dependencies do not end up in the
`linked-target-dirs` collator property. Test suite exported property
tests updated to account for the change.
