Windows: Explicitly pass PDB paths to lld-link

Browse Source 
On Windows, lld-link resolves PDB output paths using `/` and embeds the
result in the final executable, which breaks some native tooling like
WPR/WPA. This commit overrides the default behavior of lld-link by
explicitly setting the output PDB filename and binary-embedded path.
