Add tests to validate key length for clearkey plugin.

AesCtrDecryptor::decrypt() doesn't check whether the size of "key"  is
equal to 16 bytes,  which may lead to an OOB read problem in the context
of mediadrmserver. The fix is in clearkey plugin. Add tests to validate
the fix.

Test: VTS test
  adb shell /data/nativetest/VtsHalDrmV1_0TargetTest/VtsHalDrmV1_0TargetTest
