Report 3072-bit Certificate Capability

(This is a merge of go/wvgerrit/23154)

This patch updates the ClientCapabilities protobuf to match the latest
on the server side and adds plumbing to the provisioning request
process so that devices can report whether they like big certs.

Their capacity to lie remains untested.
