build: drop api 21-23 support

Drop support for Lollipop and Marshmallow.

I legit cannot build for them anymore. There's some insane dependency
tangle between Kapt and Room that makes it impossible to use anything
BUT Java 17 (maybe Java 11). If I use Java 17 or Java 11, suddenly the
whole app crashes since Lollipop and Marshmallow only support some weird
Java 8/11 chimera abomination. This issue has persisted probably since
the move to Java 11, making it basically unusable anyway, so at this point
just cut the charade and officially drop support.
