SSL: Add new extension types and ECH test

Browse source 
This commit adds a multitude of new extension types that were added in
the last few years; it also adds grease values to extensions, curves,
and ciphersuites.

Furthermore, it adds a test that contains a encrypted-client-hello
key-exchange (which uses several extension types that we do not have in
our baseline so far).
