clear the build warnings and fail on new ones

A clean build now emits no warnings of its own, and Kotlin
`allWarningsAsErrors` plus lint `warningsAsErrors` stop new ones from
sneaking back in.

- Kotlin: give SearchFilter's @StringRes parameter an explicit @param:
  target; use safe calls for File.parentFile in StringResourcesTest.
- Packaging: keep debug symbols for the prebuilt .so files that have no
  symbol table, which is what the "unable to strip" warning was about.
- Lint: move `modifier` to the first optional parameter across the Compose
  screens, use mutableIntStateOf for int state, read Resources via
  LocalResources, use the KTX Bitmap.get/String.toUri, drop the unused
  ic_action_name and ic_stat_name bitmaps and the dead -v24 qualifier on
  the notification vector, fix the pt-BR "album" accents and the unused
  Vietnamese/Thai plural quantities, and suppress the intentional
  cleartext/user-certificate, backup, exported-service and
  plural-candidate findings. Disable the version-update nags, which the
  dependency-update process owns.

The AboutLibraries plugin still resolves the variant classpaths during
configuration, so AGP keeps warning about that one; upstream in
mikepenz/AboutLibraries#1369.
