mashadercompiler: Add support for UNC paths

Browse Source 
MS DXC on Windows (at least IDxcUtils::BuildArguments) does not support forward slashes in UNC paths. This change feeds it native format with backslashes.

This makes it possible to build Linux and Windows binaries from a single source on a network share.
