The intent on these lines was to get 'psa_key_type_t' for which
'mbedtls_pk_get_key_type' should clearly be used, not
'mbedtls_pk_get_type'.

MBEDTLS_ECP_DP_MAX is defined in 'ecp.h' which is a tf-psa-crypto private
header. Instead of relying on that value define a new function named
'mbedtls_ssl_get_supported_tls_id_count' which returns the number of
entries in 'tls_id_match_table'.
Rationale: it does not have too much sense to allocate an array for TLS
IDs which is larger than the list of supported TLS IDs in the current
build.

Instead of retrieving the TLS ID using 'mbedtls_ecp_group_id', which
creates a dependency on the (now tf-psa-crypto private) 'ecp.h' header,
use PSA info to get the same result. Therefore rename the function as
'mbedtls_ssl_get_tls_id_from_curve_info'.
This new function has basically the opposite behavior than
'mbedtls_ssl_get_psa_curve_info_from_tls_id'.

All the usages of 'mbedtls_ssl_get_ecp_group_id_from_tls_id' basically
reduce to checking if a specific TLS ID is supported or not. Therefore
the function is replaced with 'mbedtls_ssl_is_tls_id_supported'.

Follow the same pattern that was used in the past to remove dependency
on MBEDTLS_RSA_C and use PSA_WANT instead.
Relying on MBEDTLS_RSA_C is fine only when builtin drivers are compiled
since all PSA_WANT are converted to legacy build symbols. However when
builtin drivers are not built (ex: in case of TF-M), then part of the code
in TLS/X509 won't be compiled because MBEDTLS_RSA_C is not set. OTOH
it's not possible to declare that symbol in a configuration file because
it's a legacy one and it will be rejected by buildtime checks.

Move back the digest update just after
the call to mbedtls_ssl_read_record().
It fits well here as we explain in the
comment associated to the call to
mbedtls_ssl_read_record() that we
update it manually.

In ssl_tls12_server.c:ssl_parse_client_hello(), remove
the code that directly reads the received data to read
the record expected to contain the ClientHello message.
The function already supported handling a ClientHello
read via mbedtls_ssl_read_record() in the following
cases:
- when the ClientHello was read as a post-handshake
message (renegotiation).
- when the ClientHello was read by
ssl_tls13_process_client_hello() during TLS 1.3 or
TLS 1.2 version negotiation.

Since the hash algorithm is known, this can be used when calling
"mbedtls_pk_can_do_psa()" to get a more accurate answer.
