57b391c8b9 Fix bugs impacting fuzzing coverage 
- Update ConvertDataToValidEnum to not use FuzzedDataProvider since it
  causes unexpected parsing results.
- Add OEMCryptoLicenseAPIFuzz::LoadLicenseWithGenericCryptoKeys so that
  generic crypto fuzz tests can load appropriate keys.
- Remove custom mutator from oemcrypto_generic_verify_fuzz because it
  provides minimal additional coverage.
- Refresh affected corpus files.

- Remove OEMCrypto state changes hidden in constructors and destructors.
- Use composition instead of inheritance to structure classes.
- Avoid calling non-trivial destructors for objects with static
  lifetime.

e3697c6595 Fix oemcrypto_decrypt_cenc_fuzz null reference 
[ Merge of http://go/wvgerrit/153669 ]

The oemcrypto_decrypt_cenc_fuzz fuzz test found a null reference error.
This adds a check to ensure that the input_buffer vector used for the
sample descriptions is not empty before attempting to access it.

6628c7f693 Update OEMCrypto test comments and logs 
Merge from Widevine repo of http://go/wvgerrit/121886

This CL merges some changes from branch rvc-dev to sc-dev
that prepared it for merge.

One change is that the unit tests now say they are part of
Android S instead of R.
