Riatre Foo a607dcec24 Normalize paths on Windows
1. Normalize paths in LSP document URIs and project root to forward
slash and uppercase drive letters.
2. Normalize paths in compile_commands.json to forward slash and
uppercase drive letters.
3. Normalize paths from directory listing to forward slash. (Drive
letter should be same as input dir path, which is already uppercase
since path of project root dir is normalized)
4. Add llvm::sys::path::convert_to_slash after certain llvm::sys::path
and llvm::fs calls.
