Increase library target SDK to 31

This only affects the default SDK level that Robolectric tests run at.
Also upgrade the Robolectric version to 4.14.1 to pick up
4f32042afe
which is needed for async `ShadowMediaCodec` support (the default in
ExoPlayer from API 31+).

Some tests fail on Robolectric at API 31. This change configures them to
continue running on API 30, so the failures can be investigated and
fixed in follow-up changes.
