Rename and document new configuration option for packing AES tables
...
This commit renames the new AES table packing option introduced in the
previous MBEDTLS_AES_PACK_TABLES and documents its use and memory vs.
speed tradeoff. It also enhances the documentation of the other
AES-related option MBEDTLS_AES_ROM_TABLES.

Add option to use smaller AES tables (table sizes reduced by 6144 bytes)
...
This patch adds MBEDTLS_AES_SMALL_TABLES option to reduce number of AES
look-up tables and thus save 6 KiB of memory. Enabling this option
cause performance hit MBEDTLS_AES_SMALL_TABLES of ~7% on ARM and ~15%
on x86-64.

Change return type of AES decrypt and encrypt
...
This patch modifies the following 2 functions in the AES module to
change the return type from void to int:
* mbedtls_aes_encrypt() -> mbedtls_internal_aes_encrypt()
* mbedtls_aes_decrypt() -> mbedtls_internal_aes_decrypt()
This change is necessary to allow users of MBEDTLS_AES_ALT,
MBEDTLS_AES_DECRYPT_ALT and MBEDTLS_AES_ENCRYPT_ALT to return an error
code when replacing the default with their own implementation, e.g.
a hardware crypto accelerator.
