EVP: Implement support for key downgrading in backends
Downgrading EVP_PKEYs from containing provider side internal keys to
containing legacy keys demands support in the EVP_PKEY_ASN1_METHOD.
This became a bit elaborate because the code would be almost exactly
the same as the import functions int EVP_KEYMGMT. Therefore, we end
up moving most of the code to common backend support files that can be
used both by legacy backend code and by our providers.
