Enable RSA-SM3 in the default provider

Enable RSA-SM3 in the default provider

It turns out that we didn't allow the combination RSA + SM3 anywhere.

This is perfectly reasonable in the FIPS module, but less so in the default
provider.  This change enables it in the default provider, and adds a simple
evp_test stanza for the RSA-SM3 signature scheme.
