Note that this is not strictly necessary as this function only copies to
the output buffer at the end. However, it simplifies testing for the
time being.
Future optimisation work could consider removing this copying.

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.

These values are not mathematically valid as signature, but as
for what it concerns with ECDSA conversion functions, 0 values
in DER format should be translated to 0 values in raw format.

Allow the function to support DER buffers than what it is nominally
required by the provided coordinates. In other words let's ignore
padding zeros in the raw number.

Add discard_early_data_record in SSL context for
the record layer to know if it has to discard
some potential early data record and how.

The test code to construct test keys and the implementation had matching
errors: both assumed that there was a PSA public key object. Fix this.

This helps in reverting the changes to test_suite_x509parse.data
when the RSA key parsing fails.

In the MBEDTLS_PK_OPAQUE, have mbedtls_pk_get_psa_attributes() require the
specified usage to be enabled for the specified key. Otherwise the following
call to mbedtls_pk_import_into_psa() is unlikely to result in a key with a
useful policy, so the call to mbedtls_pk_get_psa_attributes() was probably
an error.
Adjust the existing test cases accordingly and add a few negative test
cases.

Due to the scope reduction for
mbedtls_ssl_read_early_data(), on
server as early data state variable
we now only need a flag in the
handshake context indicating if
the server has accepted early data
or not.

This reverts commit 0883b8b625a5531f2fc8a61b6b0417f00f76f91e.
Due to the scope reduction of mbedtls_ssl_read_early_data()
it is not necessary anymore to refine the usage
of early_data_status/state rather the opposite.

In this way mbedtls_rsa_parse_pubkey() and mbedtls_rsa_parse_key()
input parameter list is the same.

Do not progress the handshake in the API, just
read early data if some has been detected by
a previous call to mbedtls_ssl_handshake(),
mbedtls_ssl_handshake_step(),
mbedtls_ssl_read() or mbedtls_ssl_write().
