This replaces the ID-based API with one that is more static linker
friendly. For ECH, it doesn't make a difference because we currently
pull in all the options we've implemented. But this means other HPKE
uses need not pull in everything ECH needs and vice versa.
Along the way, fix an inconsistency: we prefixed all the AEAD constants
with "AEAD", but not the others. Since the rest of the name already
determines everything, go with the shorter version.
