win32: rename `git_win32__canonicalize_path` The internal API `git_win32__canonicalize_path` is far, far too easily confused with the internal API `git_win32_path_canonicalize`. The former removes the namespace prefix from a path (eg, given `\\?\C:\Temp\foo`, it returns `C:\Temp\foo`, and given `\\?\UNC\server\share`, it returns `\\server\share`). As such, rename it to `git_win32_path_remove_namespace`. `git_win32_path_canonicalize` remains unchanged.
