psa_crypto_mac.c uses mbedtls_cipher_xxx() functions to perform
CMAC operations. Therefore we need to enable CIPHER_C when
PSA CMAC is builtin.

Some projects using Mbed TLS have migrated their configuration
file (config.h -> mbedtls_config.h, or MBEDTLS_CONFIG_FILE) from Mbed TLS
2.x, and kept including check_config.h. This is unnecessary since Mbed TLS
3.0, and increasingly in 3.x it may report spurious errors because the
configuration adjustments have not been done yet.

projects to include configuration adjustment headers manually, but only
partially or in the wrong order, which can result in silent inconsistencies.
Error out if this happens, with a message mentioning check_config.h since
that's the likely root cause.

Including *adjust*.h directly is likely to cause them to be applied at the
wrong time, resulting in an invalid or unintended configuration.
Including check_config.h at the wrong time is likely to cause spurious
errors.

The Mbed TLS implementations of ALG_TLS12_PRF,
ALG_TLS12_PSK_TO_MS, ALG_HKDF, ALG_HKDF_EXTRACT,
ALG_HKDF_EXPAND and ALG_PBKDF2 rely on HMAC
operations through the driver interface. Thus
if one of these algorithms is enabled and not
accelerated, we need ALG_HMAC to be enabled
(PSA_WANT_ALG_HMAC and PSA_WANT_KEY_TYPE_HMAC
defined). As HMAC operations occur through
the driver interface, HMAC operations can be
accelerated even if the caller algorithm
is not.

RSA needs ASN1 functions to parse/write private and public keys,
but there is no guards in the code for that. So we need to enable
ASN1 support whenever RSA is enabled.

removing the parts in mbedtls_ssl_session_set()

Replace MBEDTLS_PSA_COPY_CALLER_BUFFERS with inverse:
!MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS. This ensures that buffer
protection is enabled by default without any change to the Mbed TLS
config file.
