Add VTS tests for NNAPI compilation caching.

Add the following tests for compilation caching:
- validation tests
  - Test isCachingSupported
  - Test prepareModelFromCache with invalid numFd and invalid access mode
  - Test saveToCache with invalid numFd, invalid access mode,
    invalid file size, and invalid fd offset
- execution test
  - Save a mobilenet model to cache and then retrieve and run accuracy
    evaluation.
  - The same test but the file offsets for prepareModelFromCache is not at zero.
- security test
  - CompilationCachingSecurityTest.CorruptedSecuritySensitiveCache
    Randomly flip one bit of security-sensitive cache.
  - CompilationCachingSecurityTest.WrongLengthSecuritySensitiveCache
    Randomly append bytes to security-sensitive cache.
  - CompilationCachingSecurityTest.WrongToken
    Randomly flip one bit of cache token.

Test: VtsHalNeuralnetworksV1_xTargetTest with 1.2 sample driver
Test: VtsHalNeuralnetworksV1_xTargetTest with a test driver that can
      read and write cache entries
