POSIX specifies that two leading slashes have implementation-defined
interpretation, so CMake 3.31 and below did not normalize away leading
double slashes. However, most implementations simply treat a leading
`//` as just `/`, so CMake 4.0 now normalizes them away when they do not
correspond to a network path on Windows.
This change exposed that we were not normalizing `CMAKE_TOOLCHAIN_FILE`
before passing its value to `include()` the first time if it was not
passed with the `FILEPATH` or `PATH` cache entry type. Fix that.
Fixes: #27010
In commit 5aed3ee49d (cmSystemTools: Add GetLogicalWorkingDirectory,
2024-10-28, v4.0.0-rc1~528^2~6) we incorrectly trusted `PWD` to be a
normalized path so long as its realpath matches the current working
directory.
Fixes: #26870
This was accidentally dropped by commit 622596c6b2 (cmSystemTools:
Re-implement ToNormalizedPathOnDisk without translation map, 2024-10-30,
v4.0.0-rc1~528^2~5). Previously it was done by `CollapseFullPath`.
`cm::PathResolver` intentionally does not expand `~` because it makes
sense only for transforming input paths. Teach `ToNormalizedPathOnDisk`
to handle it directly.
Fixes: #26827
Add a `-LR[A][H] <regex>` flag with similar functionality to `-L[A][H]`,
but instead of listing all cached variables, it show only specific
variables that match the name regex.

For policy-specific tests, use the version before the policy was
introduced. Otherwise, use 3.5 where possible.
Also, remove `cmake_minimum_required()` and `project()` calls from
individual cases where they are handled by `CMakeLists.txt`.
The fix in commit 08aa516880 (cmake: Stop parsing after `--` when
detecting script mode, 2022-12-06, v3.26.0-rc1~216^2) only corrected the
case where `-P -- -P <arg>` occurred and not `-P -- -P -<other>`.

The `lf` and `crlf` files need to have exact LF and CRLF newlines,
respectively. Previously we used the Git `eol` attribute for this,
but occasionally the Git work tree ends up without the conversion.
It is unclear why that happens, so try to avoid the problem by
treating their content as binary instead.
