Allocate the buffer to write/read early data. That
way in ASan builds. buffer overwrite/overread can
be detected.

For negative testing of early data (tests
related to max_early_data_size in this PR), restore
the test function to write early data that was
first introduced to be able to test the reading
of early data with the writing part and was
removed (as not used anymore) by the PR 8760.

Add the reach_max flag argument for the
test13_srv_max_early_data_size test
function. Non zero value only valid in case
of TEST_EARLY_DATA_ACCEPTED scenario.

This check is intended to ensure that we do not write intermediate
results to the shared output buffer. This check will be made obselete
by generic memory-poisoning-based testing for all functions.

Same as mbedtls_ecp_write_key(), but doesn't require the caller to figure out
the length of the output and possibly distinguish between Weierstrass and
Montgomery curves.

This commit also fixes pk_psa_wrap_sign_ext() setting the RSA padding
mode so that mbedtls_pk_get_psa_attributes() correctly guesses
the PSA alg to be used.

Access the fields of `psa_key_attributes_t` directly rather than through the
`core` field. This makes the `core` field obsolete.
This commit is fully automated:
```
git ls-files '*.h' '*.c' '*.function' '*.jinja' | xargs perl -l -i -pe '$core = qr/\b(core\b|MBEDTLS_PRIVATE\(core\))/; s/->$core\./->/g; s/&(\w+)\.$core\./&$1./g; s/(\w+)\.$core/$1/g'
```

This is replaced with: mbedtls_pk_get_psa_attributes() +
mbedtls_pk_import_into_psa() + mbedtls_pk_setup_opaque().

Remove the ability to select a custom public exponent via domain parameters
in RSA key generation. The only way to select a custom public exponent is
now to pass custom production parameters to psa_generate_key_ext().
A subsequent commit will remove domain parameters altogether from the API,
thus this commit does not bother to update the documentation.

Check that the test case is hitting what it's supposed to hit, and that the
library takes the expected defensive measure.

"Key generation method" was misleading since it also applies to key
derivation. Change "key generation" to "key production", which we aren't
using yet and has roughly the right intuition. Change "method" to
"parameters" which there seems to be a slight preference for. Discussion
