[MLIR] Fix ML IR build on Windows with Visual Studio

Summary: Right now the path for each lib in whole_archive_link when MSVC is used as the compiler is not a full path - and it's not even the correct path when VS is used to build. This patch sets the lib path to a full path using CMAKE_CFG_INTDIR which means the path will be correct regardless of whether ninja, make or VS is used and it will always be a full path.
