Support dx generating multiple dex files.

Dx is now capable of generating multiple dex file in one run.
This capability is not compatible with --output=*.dex so this CL
changes the --output argument to be a directory. This CL also
includes the packaging of the multiple dex files when dx generates
more than one dex file.
