Expand AES mode macro into explicit functions

This removes the PROV_CIPHER_HW_aes_mode macro and replaces it with explicitly
written function definitions for each AES mode (ECB, CBC, CFB128, CFB8, CFB1,
OFB128, CTR).

Expanding macro-generated functions improves overall code readability, allows
code navigation tools to properly index the function signatures, and provides
clearer stack traces during debugging.
