### What changes were proposed in this pull request?
Extend support for cipher transformations in AES UDFs with Counter (CTR) &
Galois/Counter Mode (GCM) modes that provide stronger security as they use
Initialization Vector.
### Why are the changes needed?
Currently, The AES UDFs only support one cipher transformation -
AES/ECB/PKCS5Padding, which is inherently weak, as it produces the same
ciphertext for identical blocks of plain text.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Manually Tested
