Features
* The CCM and GCM modules no longer depend on MBEDTLS_CIPHER_C. People who
use CCM and GCM but don't need the Cipher API can now disable
MBEDTLS_CIPHER_C in order to save code size.

Features
* It is now possible to have AEADs support (CCM, GCM and ChaChaPoly) without
MBEDTLS_CIPHER_C. This holds both for the builtin suport (MBEDTLS_CCM_C,
MBEDTLS_GCM_C and MBEDTLS_CHACHAPOLY_C) as well as the PSA one
(PSA_WANT_ALG_CCM, PSA_WANT_ALG_GCM, PSA_WANT_ALG_CHACHA20_POLY1305).
On the PSA side this means that it is possible to enable
MBEDTLS_PSA_CRYPTO_C without MBEDTLS_CIPHER_C if none of the
non-authenticated ciphers is enabled.

Features
* Fewer modules depend on MBEDTLS_CIPHER_C, making it possible to save code
size by disabling it in more circumstances. In particular, the CCM and
GCM modules no longer depends on MBEDTLS_CIPHER_C. Also,
MBEDTLS_PSA_CRYPTO can now be enabled without MBEDTLS_CIPHER_C if all
unauthenticated (non-AEAD) ciphers are disabled, or if they're all
fully provided by drivers. See docs/driver-only-builds.md for full
details and current limitations; in particular, NIST_KW and PKCS5/PKCS12
decryption still unconditionally depend on MBEDTLS_CIPHER_C.
