build: Bump target and compile SDK to 37 (JAVA-648) (#5796)

* build: Bump target and compile SDK to 37

Raise targetSdk and compileSdk from 36 to 37 and remove the temporary
GradleDependency lint suppression that was in place only until this bump.

API 37 makes MediaCodecInfo.getVideoCapabilities() nullable, so guard the
access in SimpleVideoEncoder to keep it compiling.

* build: Drop obsolete OldTargetApi lint suppression

Now that the integration test modules target API 37, lint no longer flags
OldTargetApi, so remove the temporary suppression added while they were on 36.
