Cover the last remaining interfaces across libraries/audio, libraries/cachestore,
libraries/indicator, libraries/slashcommands, libraries/voiceplayer and
services/apperror, with their members and parameters.
This completes the effort: all 222 in-scope interfaces and their 820 members in
the 60 api modules that hold any now carry documentation.
Notable points: CacheStore applies no expiry of its own and only records when each
entry was written, leaving staleness to the caller; SlashCommandService.parse
never throws, returning NotACommand for ordinary text and an error case for a
malformed command.

* Avoid SQLCipher key derivation by manually providing the generated as a raw key: this needs a series of DB re-key operations, performed as part of a 'dummy' DB migration
* Set key generation length to 32 bytes in `RandomSecretPassphraseProvider`.
* Use `ClientSecret` for handling the keys for SQLCipher. Move `ClientSecret` to `:libraries:androidutils` so it's shared.
