The calculation of the expected key size when not using the test_size_function
was not correct. The function has now been updated to handle all cases
properly to ensure the expected key size is correct for key pairs, public
keys, and symmetric keys.
Cleaned up some comments and removed unused includes.

Previous guard was using original naming and did not
get updated to the new name. Guard is now using correct
definition of TEST_DRIVER_KEY_CONTEXT_SIZE_FUNCTION.

Removed TBD comment that is no longer relevant since
that portion of the code has been updated.

Updated get_expected_key_size in psa_crypto_driver_wrappers to properly
handle using the new size_function from PSA crypto drivers. Created
initial infrastructure to support size_function for the PSA crypto
drivers.

This change fixes the decrypt cipher setup function to return the
appropriate error code of PSA_ERROR_NOT_SUPPORTED instead of
PSA_ERROR_BAD_STATE for invalid locations when the setup call is made.

With the new feature MBEDTLS_PSA_CRYPTO_CONFIG, needed to
add support that when the feature is disabled, if there
are defines like MBEDTLS_ECDSA_C defined, then the PSA_WANT_
equivalent define is also enabled. This ensures the guards in
the library psa_crypto will work properly.
Also fixed an error return code in the driver wrapper for cipher
encrypt setup so it will properly pass unit tests.
Ensured config.py full works properly with the new
MBEDTLS_PSA_CRYPTO_CONFIG, it should not be set when the full
option is used.

Added zeroization of the wrapper context on failure/abort, and reliance on
the crypto core to not call an uninitialised wrapper.

Trying to compile in the PSA accelerator test driver under MBEDTLS_TEST_HOOKS
turned out to be awkward regarding existing builds. We'll put it under a
custom (not in config.h) define instead, since it's something that only
should happen in test.

This is a more natural place for handling the drivers belonging to the
'previous' SE driver spec. It makes for a cleaner psa_crypto.c, and
potentially an easier overview of how to migrate from the old SE driver
interface to the 'opaque accelerator' interface.
