Switch HPKE to a three-parameter output buffer.

This is a little tedious but aligns with some of our other
variable-length parameters. This is in preparation for making the HPKE
APIs KEM-agnostic, so we don't need to make so many variations on the
HPKE functions for each KEM. (Especially if we ever need to implement
SetupPSK*, SetupAuth*, or SetupAuthPSK*.)
