Check APF version, VSR API level, and Android version

This commit introduces checks for APF version, VSR API level,
and Android version to decide whether an APFv4 test should be
run, skipped, or fail:
* If Android version is less than V, skip the test
* If VSR API level is greater than or equal to 14 and APF
  version is less than 4, fail the test
* Otherwise, if APF version is less than 4, skip the test
