Since macOS 12.0 deprecated the tools needed to attach a SLA to a
`.dmg`, we should no longer do this by default. Add a policy to
change the default to off.

Blame shows EasyGit was part of initial FindGit 11 years ago.
I can hardly find Easy Git as a package. Given that Git is vital
for many complex CMake projects, it seems good to ensure CMake
FindGit is finding a Git program likely to work.
Crucial CMake modules like FetchContent also use FindGit, emphasizing
the importance of having a Git executable with proper functionality.
When the Apple linker sees -headerpad_max_install_names and
bitcode is enabled with a flag like -fembed-bitcode, it issues a warning
and ignores the -headerpad_max_install_names flag. This causes
unrelated compiler and linker flag checks to fail for valid flags.
In f745e0497e (CheckCompilerFlags: Catch linker warning about ignored
flags, 2022-01-03), we started detecting linker warnings, which caused
a regression for projects that were setting -fembed-bitcode in their
CMAKE_CXX_FLAGS or similar. Prevent that regression by removing
the -headerpad_max_install_names linker flag when we know it will
warn and be ignored anyway.

Issue: #23408
Fix a typo from commit 660e0d80ae (internal/CheckCompilerFlag: rely on
common configuration, 2022-01-12, v3.23.0-rc1~124^2~1) that caused
locale environment variables to not be restored after they are set
during the check.
This makes it far clearer that `<depends>` is a list up front instead of
burying the lede because a list is generally "trivially true" in CMake[1].
Also clarify that `<force>` is only available as a local variable and if
queried outside of the "scope" of the `cmake_dependent_option` call,
will get the stored user cache value.
[1] The exception being when the last entry ends in `-NOTFOUND`.

Revert commit dd9584b352 (GNUInstallDirs: Apply Debian multiarch LIBDIR
to more prefixes, 2021-11-19, v3.23.0-rc1~323^2). There are separate
problems with activating multiarch `LIBDIR` for each prefix it added:
* Prefix `/` is often used to stage an installation with `DESTDIR`
for inclusion in a tarball package or similar.
* Prefix `/usr/local` is the default `CMAKE_INSTALL_PREFIX`, causing
the multiarch `LIBDIR` to be cached after the first configuration,
even if the prefix changes later.
Revert the change for now, except for the documentation update.
Further discussion will be needed to select a way to enable
multiarch `LIBDIR` for `/` and `/usr/local`.

Issue: #19698
`CMAKE_<LANG>_COMPILER` may be a list if it was defined by a toolchain
file. In this case we move the args to `CMAKE_<LANG>_COMPILER_ARG1`.
If `CMAKE_<LANG>_COMPILER` is not a list, then it might have been cached
by a previous run that split the `CC` or `CXX` environment variable into
`CMAKE_<LANG>_COMPILER` and `CMAKE_<LANG>_COMPILER_ARG1`. In this
latter case, avoid clobbering `CMAKE_<LANG>_COMPILER_ARG1`.
