Subject: [PATCH] verify ringtone URI before setting
Similar to ag/24422287, but the same URI verification should be done in
SettingsProvider as well, which can be called by apps via
Settings.System API or ContentProvider APIs without using
RingtoneManager.
BUG: 227201030
Test: manual with a test app. Will add a CTS test.
(cherry picked from https://googleplex-android-review.googlesource.com/q/commit:1b234678ec122994ccbfc52ac48aafdad7fdb1ed)
