Introduce "enable_r8_turbo_builds" gradle property

Use a separate sourceSet for files that have been modified when doing
incremental builds. Speeds up compile times where the list of files
isn't changed from 1-2 minutes -> 1-2 seconds.

Caveat: Unmodified sources that depend on modified ones will *not be
rebuilt* when modified sources change. This is where the speed-up comes
from, but can lead to runtime crashes if signatures change without
references to them being updated.

I've so far not actually hit this caveat, as IntelliJ is quite good at
pointing out problems without needing to do a compile.
