EGL BlobCache: Add CRC check to multifile
Apply a CRC check during file write, ensuring it is
the last thing applied to the file.
During initialization, verify the contents of the file
and remove if CRC doesn't match.
Add a new test (ModifiedCacheEndMisses) that modifies
the end of the entry and ensures no cache hit.
Test: pubg_mobile_launch ANGLE trace
