Having a non-const `key` parameter was anotherf defect of
mbedtls_ecp_write_key(). Take this opportunity to fix it.

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.

Re-restore mbedtls_x509_string_to_names() to public as our example
programs use it, and it is the reverse of mbedtls_x509_dn_gets().
Add a docstring, so that it is a properly documented public function.

It means that mbedtls_psa_get_random() goes through the PSA interface
all the times. Fallbacks to CTR_DRBG or HMAC_DRBG are still possible,
but that depends on how the crypto provider is built.

This function should be internal, being exposed only via functions like
mbedtls_x509write_crt_set_subject_name().

Document and test the current behavior, even if it is weird:
* For Weierstrass keys, the error is MBEDTLS_ERR_MPI_BUFFER_TOO_SMALL,
not MBEDTLS_ERR_ECP_BUFFER_TOO_SMALL.
* For Weierstrass keys, a smaller output buffer is ok if the output fits.

When exporting a key, MBEDTLS_ERR_ECP_FEATURE_UNAVAILABLE should not happen.
This error indicates that the curve is not supported, but that would prevent
the creation of the key.

Now that we have padding verification after decryption and since
this can be used to validate the password as well there is no
need to parse ASN1 content any more, so we can simplify/remove
that dependency.

Remove exception warnings about PKCS1v1.5, since now both padding
formats are treated properly no matter if USE_PSA_CRYPTO is
defined or not.

The default window size as default is set to the value that believed to
give the best performance. Since the algorithm changed, the fastest
window size has changed as well.

MBEDTLS_PK_WRITE_C requires MBEDTLS_ASN1_WRITE_C, but there is no
corresponding check in check_config.h. In addition, corresponding
documentation for `Requires` is updated in mbedtls_config.h.

- check_config.h: combine separate check for MBEDTLS_PK_PARSE_C
- mbedtls_config.h: update documentation for `Requires`

In pk.h, MBEDTLS_PK_HAVE_ECC_KEYS is enabled if ECP_C is defined or
USE_PSA_CRYPTO && PSA_WANT_KEY_TYPE_ECC_PUBLIC_KEY are defined.
But this logic is duplicate with its definition in
config_adjust_legacy_crypto.h.

When PK_HAVE_ECC_KEYS is set with PK_[PARSE/WRITE]_C, it needs OID_C
to be enabled. This commit adds proper checks in check_config.h
