MINOR: ssl: support curve fetches with AWS-LC API 30

Enable ssl_fc_curve and ssl_bc_curve with AWS-LC API 30-34, including
AWS-LC 3.0.0, using SSL_get_group_id() and SSL_get_group_name() instead
of SSL_get_negotiated_group(), which requires API 35.

Map NIST curve group IDs to OpenSSL short names to keep the output
consistent with newer AWS-LC versions. Preserve native names for other
groups, including post-quantum and hybrid groups.

Update the compatibility documentation and enable the curve regression
tests for AWS-LC API 30.
