- MBEDTLS_GENPRIME is removed because now we rely on predefined
RSA keys.
- MBEDTLS_RSA_GEN_KEY_MIN_BITS is replaced with RSA_KEY_SIZE which
is set on top of test_suite_pk to a value which is supported
in the predefined_keys[] array.

Remove static declaration of look-up table from test_suite_pk
and generate it automatically with Python.

This is to manage RSA and EC keys in the same way in order to
prepare for the following commits.

asymmetric_key_data.py already provides EC/RSA key pair values that
are suitable for generate_test_keys.py. So instead of re-generating
the keys using gen_key program, we use those keys.
This commit also:
- extends asymmetric_key_data.py to introduce
RSA bit sizes that are used in test_suite_pk but were missing from
asymmetric_key_data.py.
- updates test_keys.h with new keys.

- remove BEGIN_FILE/END_FILE lines from output header file.
- add single disclaimer at the beginning of the file instead
of having it repeated for every array.
- improved exception message for missing key generation program.
This commits also regenerates "test_keys.h" in order to fully
comply with the new format.

Now that key generation has been replaced with parsing predefined
keys, guards for MBEDTLS_PK_PARSE_C need to be added in test
code.
This commits also removes remaining usage of GENPRIME.

This commit adds "generate_test_keys.py" script to generate
predefined keys used in test_suite_pk. Keys are generated with
"programs/pkey/gen_key" tool and converted to C array using
the python script.
tests/src/test_keys.h is automatically generated using the
above mentioned script.
test_suite_pk is updated in order to use the new format.

Instead of using PK module to import/export the key in a PSA friendly
format:
- for RSA keys we use the DER input data directly;
- for EC keys we extract the private key manually.
This helps avoiding dependencies from PK_WRITE and PK_PARSE.

Add pk_info parameter in order to ease the requirements on the provided
PK context. Now it can simply be initialized, but not setup.

This helps dropping dependency on FS_IO.
This commit also removes DER files that were previusly added and which
are not more needed/used.

If the public key is exported with mbedtls_pk_write_pubkey_der()
it should be re-imported with mbedtls_pk_parse_public_key().
Alternative options (when PK_WRITE is not defined), i.e.
mbedtls_ecp_point_write_binary() and mbedtls_rsa_write_pubkey(),
export the key in a different format which cannot be parsed by
pk_parse module so mbedtls_ecp_point_read_binary() and
mbedtls_rsa_parse_pubkey() should be used respectively in this
case.

Use mbedtls_test_key_consistency_psa_pk() to verify that the
generated PK contexts match with the original PSA keys instead
of doing sign/verify and encrypt/decrypt.

This bug was not found until now because:
- !PK_[WRITE|PARSE]_C is only tested in component_full_no_pkparse_pkwrite()
- the test only case concerning RSA key had MBEDTLS_PK_WRITE_C as dependency
so it was not executed in that component.
