PROV: Add SM2 encoders and decoders, as well as support functionality
The EC KEYMGMT implementation handled SM2 as well, except what's
needed to support decoding: loading functions for both EC and SM2 that
checks for the presence or absence of the SM2 curve the same way as
the EC / SM2 import functions.
