Fix encryption/decryption of large blocks.
There's a long-standing bug (since ~Marshmallow) that causes
AndroidKeyStore to truncate large (>64 KiB) blocks of data. This can
be avoided by callers by processing data in smaller chunks, and
smaller chunks are more memory-efficient while not being much (if any)
more time-efficient. But, Keystore should handle large blocks
correctly. This CL adds a test to all block cipher tests that
attempts to encrypt and then decrypt a 100 KiB block.
Bug: 123391046
Test: CtsKeystoreTestCases
