Move all binding containers to a di package and normalize their method names

Every @BindingContainer now lives in a di subpackage, in a file named after
it. Containers that were declared inside a shared file (SimplePlayer.kt,
LockScreenConfig.kt, VoiceMessagePresenter.kt, TimelineItemPresenterFactories.kt,
MediaItemPresenterFactories.kt) are extracted into their own file.

Method names are made consistent too:
- @Binds functions are named bind<ConcreteParameterType>, fixing three that
  named something else (notably RoomAliasResolverBindingContainer, whose
  provider was still called providesJoinRoomPresenterFactory).
- @Provides functions are named after what they provide, and all use the
  provides prefix rather than a mix of provide and provides.

ANDROID_KEYSTORE moves back to the cryptography impl package, next to
KeyStoreSecretKeyRepository which uses it; it is not DI specific and would
otherwise be unreachable from there.

No behaviour change: Metro discovers containers via @ContributesTo and does
not care about method names, so the only call site to follow was in
DefaultVoiceRecorderTest.
