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.

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.

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.

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.

Move the *INDENT-ON* annotation to the end of the file so that
uncrustify does not restyle the later sections (since it introduces a
risk of future problems).

The inline assembly defined in bn_mul.h confuses code style parsing,
causing code style correction to fail. Disable code style correction for
the whole section gated by "#if defined(MBEDTLS_HAVE_ASM)" to prevent
this.

Some PSA curves' symbols (PSA_WANT_) were not matching the corresponding
MBEDTLS_ECP_DP_. This was fixed together with the removal of extra code
when DEBUG_C is not enabled.

The following code:
#ifndef asm
#define asm __asm
#endif
causes Uncrustify to stop correcting the rest of the file. This may be
due to parsing the "asm" keyword in the definition.
Work around this by wrapping the idiom in an *INDENT-OFF* comment
wherever it appears.
