path: use OS-specific function in MkdirAll, don't always keep trailing slash

CL 86295 changed MkdirAll to always pass a trailing path separator to
support extended-length paths on Windows.

However, when Stat is called on an existing file followed by trailing
slash, it will return a "not a directory" error, skipping the fast
path at the beginning of MkdirAll.

This change fixes MkdirAll to only pass the trailing path separator
where required on Windows, by using an OS-specific function fixRootDirectory.

Updates #23918
