Adapt special case framework support.

I'm adding a annotation processor to the framework target that does not
run as part of the main build, but only for a parallel build target
framework-annotation-proc, which is identical to framework except that it
also runs an annotation processor. Update build rules to be aware of this
target so that it builds successfully.

Test: m framework-annotation-proc
