[mlir] Fix linking with LLD

The issue is that /WHOLEARCHIVE is interpreted differently in LLD, which needs the same exact path as the .lib; whereas link.exe can take the library name, withoutout a path or extension, if that was already supplied on the cmd-line. I'll write a follow-up patch to fix the issue in LLD.
