Align remaining TLS ECDH APIs on "group" terminology
This adds "group" versions of our codepoint-based APIs. This is mostly
because it looks weird to switch terminology randomly in the
implementation. See I7a356793d36419fc668364c912ca7b4f5c6c23a2 for
additional context.
I've not bothered renaming the bssl_shim flags. That seems a waste of
time.
