`mbedtls_test_err_add_check` was previously incorrectly throwing an error if
both error codes were correct and valid pure error codes. This change fixes
that behaviour to correctly throw errors when invalid combinations are found.

Adds a macro (`MBEDTLS_ERR_ADD`) to add error codes together and check that the
result will not be corrupted. This additional check is only enabled during
testing when `MBEDTLS_TEST_HOOKS` is defined.
Also includes a reference usage example in `rsa.c` where two high-level error
codes could be incorrectly added together under the right conditions. This now
ensures that when this error occurs during testing it will be correctly
reported.

Corresponds better to the validation done in other modules of PSA Crypto.

The aead_encrypt and aead_decrypt are lightly
simplified and tweaked versions of test_suite_psa_crypto
test functions with the same names.

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.

As we want to do Mbed TLS aead operations as a
driver does, aead operations should not access
the key slot as key slots are not available to
drivers.
Second step in this PR: do not unlock the key slot
as part of operation abort.

Fix the subtraction in fix_negative, which was incorrectly not looking
for a carry. This caused the result to be wrong when the least
significant limb of N was 0. Fix#4296.
The bug was introduced by d10e8fae9e
"Optimize fix_negative". Thanks to Philippe Antoine (catenacyber) for
reporting the bug which was found by his EC differential fuzzer.
