Fix bug #81068: Fix possible use-after-free in realpath_cache_clean()

If ZTS is enabled, this can cause cwd_globals_ctor() to be called
multiple times, each with a freshly allocated virtual_cwd_globals
instance. At shutdown time however, cwd_globals_dtor() will call
realpath_cache_clean(), which then possibly cleans up the same
realpath_cache instance more than once. Using AddressSanitzer, this
shows up as a heap use-after-free.

To avoid this, add a helper function to do the actual work on one
instance of a realpath_cache, and call it both from cwd_globals_dtor()
and realpath_cache_clean(). The former uses the virtual_cwd_globals
parameter passed in via the destructor, the latter uses the CWDG()
macro.

Fix #80960: opendir() warning wrong info when failed on Windows

Firstly, we must not forget to set appropriate error codes for "manual"
checks in `virtual_file_ex()`.

Secondly, we must not call `php_error_docref2()` for warnings regarding
unary functions; thus, we introduce `php_win32_docref1_from_error()`.

Closes GH-6872.

While that is basically correct, some reparse points may point to
inaccessible system folders (e.g. `IO_REPARSE_TAG_DEDUP` points to
"\System Volume Information"). Since we don't know details about
arbitrary reparse points, and are mainly interested in nested symlinks,
we take a step back, and only resolve `IO_REPARSE_TAG_SYMLINK` for now.

Close GH-6354.
