Instead of passing the size of the whole structure, just pass the data
length and let the implementation worry about adding the size of the
structure. The intent with passing the structure size was to allow
the client code in a client-server implementation to know nothing
about the structure and just copy the bytes to the server. But that was not
really a useful consideration since the application has to know the
structure layout, so it has to be available in the client implementation's
headers. Passing the method data length makes life simpler for everyone by
not having to worry about possible padding at the end of the structure, and
removes a potential error condition
(method_length < sizeof(psa_key_generation_method_t)).

Implement and unit-test the new functions psa_generate_key_ext() and
psa_key_derivation_output_key_ext(), only for the default method.

Do for public keys what
"Fix mbedtls_pk_get_bitlen() for RSA with non-byte-aligned sizes"
did for key pairs.

Add non-regression tests. Update some test functions to not assume that
byte_length == bit_length / 8.

The added comma is needed so that these tests match the regex exceptions
in analyze_outcomes.py.
Moved the Encryption tests so that they are separate to decryption.

Make it clearer where the magic number chosen for entropy_len actually
comes from, and why we chose this value.

Normally, if an elliptic curve is enabled in the legacy API then it's also
enabled in the PSA API. In particular, if the legacy API has at least one
curve then that curve also works with PSA. There is an exception with
secp224k1 which PSA does not support. In a build with secp224k1 as the only
legacy curve, MBEDTLS_PK_HAVE_ECC_KEYS is enabled (because you can use the
curve through PK) but PSA does not support any elliptic curve, so we can't
run PK-PSA bridge tests.

The only real contraint on the raw buffer is that it is large
enough to contain 2 coordinates. Larger buffers are therefore
allowed and the extra data will simply be ignored.
Note = trying to impose a strict sizing on the raw buffer causes
several failures in test suites. This suggests that it is
quite common to use larger buffer to store raw signatures.
