The reference session cache implementation may end up storing multiple
sessions associated to the same session ID if the set()-call for the
second session finds an outdated cache entry prior to noticing the entry
with the matching session ID. While this logically overwrites the existing
entry since we always search the cache in order, this is at least a waste
of resources.
This commit fixes this by always checking first whether the given ID is
already present in the cache.
It also restructures the code for easier readability.
Fixes#4509.

This commit improves the readability of the SSL session cache
reference implementation of mbedtls_ssl_cache_set() by moving
the logic for finding a suitable free slot for the session to
store into a static helper function.

Session-ID based session resumption requires that the resumed session
is consistent with the client's ClientHello in terms of choice of
ciphersuite and choice of compression.
This check was previously assumed to be performed in the session cache
implementation, which seems wrong: The session cache should be an id-based
lookup only, and protocol specific checks should be left to Mbed TLS.
This commit
- adds an explicit ciphersuite and compression consistency check after
the SSL session cache has been queried
- removes the ciphersuite and compression consistency check from
Mbed TLS' session cache reference implementation.

Add library/*.h to the list of files scanned for enums in
list-enum-consts.sh, consistent with the changes made to
list-macros.sh.
This is needed to ensure that check-names.sh passes for the MPS
trace enums.

Capitalise the MPS trace macros, as per the coding style (and make a slight
change to naming convention to avoid a name collision).

This was a mistake, there's no reason for the dependencies to be
commented out. The dependencies on PSA_WANT_ALG_EDDSA aren't actually
necessary at the moment, but they might be in certain configurations
if some macros are simplified to save code size.

Fix expected error code when importing a persistent key or
registering a key with an invalid key identifier:
PSA_ERROR_INVALID_ARGUMENT instead of PSA_ERROR_INVALID_HANDLE.

Add negative tests checking that psa_copy_key()
returns PSA_ERROR_INVALID_ARGUMENT when passed in
an invalid key identifier or key lifetime for the
target key.
