If we enabled AES_DECRYPT_ALT and either AES_SETKEY_DEC_ALT or
AES_USE_HARDWARE_ONLY, this means RSb and RTx are not needed.
This commit extends how we guard RSb and RTx for the combinations of
these configurations.

Mainly done by the commands, with some manual adjust.

Rename mbedtls_ssl_tls13_conf_max_early_data_size as
mbedtls_ssl_conf_max_early_data_size since in the future
this may not be specific to TLS 1.3.

This tied input and output buffers together in
awkward pairs, which made the API more difficult
to use.

If MBEDTLS_BLOCK_CIPHER_NO_DECRYPT is enabled, but decryption is
still requested in some incompatible modes, we return an error of
FEATURE_UNAVAILABLE as additional indication.

Since we are internal rather than user-facing,
PSA_ERROR_CORRUPTION_DETECTED makes more sense than
PSA_ERROR_BUFFER_TOO_SMALL. Whilst it really is a buffer that is too
small, this error code is intended to indicate that a user-supplied
buffer is too small, not an internal one.

Zero-length buffers should be represented in the
psa_crypto_buffer_copy_t struct as NULL if it was created in
psa_crypto_alloc_and_copy(), so reject non-NULL zero-length buffers.

If we have a copy buffer but no original to copy back to, there is not
much sensible we can do. The psa_crypto_buffer_copy_t state is invalid.

Since it is implementation-dependent whether
malloc(0) returns NULL or a pointer, explicitly
represent zero-length buffers as NULL in the
buffer-copy struct, so as to have a uniform
behaviour.

Add function prototypes for psa_crypto_alloc_and_copy() and
psa_crypto_alloc_and_free(), along with the necessary state struct.
