Reland: Pass jars with resources to R8
R8 will parse proguard files out of resources in injars. Use the jar
with resources instead of the classes jar so that R8 can see the
proguard files.
R8 fails when an input jar contains dex files, so filter out dex files
from the input jar before passing it to r8.
This relands Ibb870ee9c70470336f542a3b7542dab86716dbf8 with a fix to
move the temporary input jar outside the output directory. Putting it
in the output directory interacted poorly with RBE in local comparison
mode, which incorrectly deleted the output directory.
