Add check for unsupported partial key type acceleration

Browse Source 
Tested manually as follows: in
component_test_psa_crypto_config_accel_ecc_some_key_types, modify
loc_accel_list to remove one of the key types between
helper_libtestdriver1_make_drivers and helper_libtestdriver1_make_main,
and observe that the 2nd build fails with the expected #error.

Note: removing one of the key types before
helper_libtestdriver1_make_drivers causes the build of libtestdriver1 to
fail, which is quite acceptable, just not what we're trying to observe.
