hidgd: add TPM functions to give correct registration
Use the TPM to obtain a static EC key at 81000101 as the public point
and signature for registration. We assume the DER certificate is a
signed version of this. Currently, I'm just using a self signed
certificate which the webauthn demo site seems to accept.

This commit of code passes registration, but obviously not login
because signing is currently unimplemented.
