  [clang][DependencyScanner] Remove unused -fmodule-map-file arguments (#80090)

Since we already add a `-fmodule-map-file=` argument for every used
modulemap, we can remove all `ModuleMapFiles` entries before adding
them.

This reduces the number of module variants when `-fmodule-map-file=`
appears on the original command line.
