Revert "Re-land sksl fragment processor support"

This reverts commit c070939fd1a954b7a492bc30f0cf64a664b90181.

Reason for revert: 

This has some knock-on effects in the generation of Android.bp from our GN files.  See gn/gn_to_bp.py?  We're seeing things like "tmp/tmpsBVycx/gen/" end up in the include search path in Android.bp, which obviously don't exist there...
