Do check the return values in our code. We were already doing that

Ensure that the documentation of fields affected by
"mbedtls_ssl_config: Replace bit-fields by separate bytes"
conveys information that may have been lost by removing the exact size of
the type. Extend the preexisting pattern "do this?" for formerly 1-bit
boolean fields. Indicate the possible values for non-boolean fields.

This slightly increases the RAM consumption per context, but saves code
size on architectures with an instruction for direct byte access (which is
most of them).
Although this is technically an API break, in practice, a realistic
application won't break: it would have had to bypass API functions and rely
on the field size (e.g. relying on -1 == 1 in a 1-bit field).

Move small fields first so that more fields can be within the Arm Thumb
128-element direct access window.
Keep the int section after the pointer section: moving int fields first cost
a few bytes on the reference baremetal-m0plus build.
The ordering in this commit is not based on field access frequency.

Move fields around to have fewer accesses outside the 128-element Thumb
direct access window.
In psa_hkdf_key_derivation_t, move the large fields (output_block, prk,
hmac) after the state bit-fields. Experimentally, it's slightly better
to put hmac last.
Other operations structures don't go outside the window, at least when not
considering nested structures.

Several files among include/psa/crypto_*.h are not meant to be included
directly, and are not guaranteed to be valid if included directly. This
makes it harder to perform some static analyses. So make these files more
self-contained so that at least, if included on their own, there is no
missing macro or type definition (excluding the deliberate use of forward
declarations of structs and unions).

Previously passing a NULL or zero length password into either
mbedtls_pkcs12_pbe() or mbedtls_pkcs12_derive() could cause an infinate
loop, and it was also possible to pass a NULL password, with a non-zero
length, which would cause memory corruption.
I have fixed these errors, and improved the documentation to reflect the
changes and further explain what is expected of the inputs.

The current definition of PSA_ALG_IS_HASH_AND_SIGN includes
PSA_ALG_RSA_PKCS1V15_SIGN_RAW and PSA_ALG_ECDSA_ANY, which don't strictly
follow the hash-and-sign paradigm: the algorithm does not encode a hash
algorithm that is applied prior to the signature step. The definition in
fact encompasses what can be used with psa_sign_hash/psa_verify_hash, so
it's the correct definition for PSA_ALG_IS_SIGN_HASH. Therefore this commit
moves definition of PSA_ALG_IS_HASH_AND_SIGN to PSA_ALG_IS_SIGN_HASH, and
replace the definition of PSA_ALG_IS_HASH_AND_SIGN by a correct one (based
on PSA_ALG_IS_SIGN_HASH, excluding the algorithms where the pre-signature
step isn't to apply the hash encoded in the algorithm).
In the definition of PSA_ALG_SIGN_GET_HASH, keep the condition for a nonzero
output to be PSA_ALG_IS_HASH_AND_SIGN.
Everywhere else in the code base (definition of PSA_ALG_IS_SIGN_MESSAGE, and
every use of PSA_ALG_IS_HASH_AND_SIGN outside of crypto_values.h), we meant
PSA_ALG_IS_SIGN_HASH where we wrote PSA_ALG_IS_HASH_AND_SIGN, so do a
global replacement.

mbedtls_ssl_conf_groups allows supported groups for key
sharing to be configured via their IANA NamedGroup ID.
This is added in anticipation of PQC and Hybrid key
sharing algorithms being integrated into Mbed TLS.
mbedtls_ssl_conf_curves is deprecated in favor of
mbedtls_ssl_conf_groups. handshake_init has been
modified to translate and copy curves configured
via conf_curves into a heap allocatied array of
NamedGroup IDs. This allows the refactoring of code
interacting with conf_curve related variables (such
as curve_list) to use NamedGroup IDs while retaining
the deprecated API.
