[build] Add sourcelink support for windows pdbs (#2592)

SourceLink embeds the git repo and hash into the pdbs, which allows VS to get the source files exactly matching a pdb directly from github.

Only VS and WinDbg are supported currently, but there are issues in the vscode tools repo to enable it there.
