This path updates the clean-up logic of to individually
free each of the the group's structure members
rather than invoke `mbedtls_ecp_group_free()`.

This patch adjusts the logic, so that the method is included,
when the following components are enabled:
* MBEDTLS_ECP_DP_CURVE448_ENABLED
* MBEDTLS_ECP_DP_CURVE25519_ENABLED
* ECP_LOAD_GROUP

This patch updates the method to not free the `grp->P`
and `grp->N` structure members.
The contents of `P` and `N` are stored in static memory at
`curve448_p/n` and `curve25519p/n` and no longer dynamically
allocated.

This patch adds two embedded constants used by `ecp_use_curve448()`.
The method has been updated to read that into an mpi instead of
calculating it on the fly.

This PR needs some change logs but there is a follow-up PR (issue #6935) that would change the change logs we would had here thus we will do them all while working on #6935.
When ticket_flags used as parameter, use unsigned int,
instead of uint8_t or mbedtls_ssl_tls13_ticket_flags.Also
remove the definition of mbedtls_ssl_tls13_ticket_flags.

Now the config dependencies used for ticket_flags
test cases are TLS 1.2 specified. Correct them to

Return MBEDTLS_ERR_ERROR_GENERIC_ERROR when ticket_flags
are not compatible with advertised key exchange mode.

Ticket flags is quite generic and may make sense in the
future versions of TLS or even in TLS 1.2 with new
extensions. This change remane the ticket_flags helper
functions with more generic `mbedtls_ssl_session` prefix
instead of `mbedtls_ssl_tls13_session`.

Handshake parameter field, tls13_kex_mode is only valid when
MBEDTLS_SSL_TLS1_3_KEY_EXCHANGE_MODE_SOME_PSK_ENABLED is set.
So, any functions / calls should be guarded by this macros.

Move the kex mode check in ticket_flags to
ssl_tls13_offered_psks_check_identity_match_ticket and add new error
'MBEDTLS_ERR_SSL_TICKET_INVALID_KEX_MODE' to indicate the check
failure.

key exchange modes in Pre-Shared Key Exchange Modes extension. The
incompatible ticket should be mark as not matched.

We're including psa/crypto_values.h, which defines the necessary error
codes. Remove redundant definitions, which hurt because they need to be
styled in exactly the same way (same presence/absence of spaces between
tokens).
This completes the fix of https://github.com/Mbed-TLS/mbedtls/issues/6875.
