This is automatic in CPython but not guaranteed by the language. Be friendly

The test is based on the AEAD multi-part test, re-using the
design on aead_multipart_internal_func() to test differnet
sequence of psa_mac_update() for MAC update or verify.

Running mypy was optional for a transition period when it wasn't installed
on the CI. Now that it is, make it mandatory, to avoid silently skipping an
expected check if mypy doesn't work for some reason.

Sign rsa is not thread safe. Remove it from current code.
And a thread-safe version should be re-introduce in future.

The storage format comparison has a dual purpose: detect format changes that
lead to a loss of backward compatibility, and detect loss of test coverage.
For loss of backward compatibility, the read tests are the relevant ones.
For loss of test coverage, all generated test cases are potentially
relevant, but this script currently focuses on storage format (where a loss
of test coverage may be a symptom of a loss of backward compatibility).
Therefore, storage format test comparison now looks at manually written
storage format tests, but only if they're read tests.

Expand abi_check.py to look for backward incompatibilities not only in
the interface exposed to application code (and to some extent driver
code), but also to the interface exposed via the storage format, which
is relevant when upgrading Mbed TLS on a device with a PSA keystore.
Strictly speaking, the storage format checks look for regressions in
the automatically generated storage format test data. Incompatible
changes that are not covered by the generated tests will also not be
covered by the interface checker.
A known defect in this commit is that the --brief output is not brief
for storage format checks.

This way we can add other checks and only run a subset of all the
checks. The default remains to run all the checks.
I made separate options for API and ABI, but since we use the same
tool for both and it doesn't have an obvious way to check only API or
only ABI, the two options must be both enabled or both disabled.

Make `PSA symetric decrypt: CCM*-no-tag, input too short (15 bytes)`
depend on MBEDTLS_CCM_C otherwise the multi-part test fails on
the missing CCM* instead on the input length validity for CCM*.
