[ClangPackager] Add an option to extract inputs to an archive

Currently we simply overwrite the output file if we get muliple matches
in the fatbinary. This patch introduces the `--archive` option which
allows us to combine all of the files into a static archive instead.
This is usefuly for creating a device specific static archive library
from a fatbinary.
