verifiers: Core TPM support

Add support for performing basic TPM measurements. Right now this only
supports extending PCRs statically and only on UEFI. In future we might
want to have some sort of mechanism for choosing which events get logged
to which PCRs, but this seems like a good default policy and we can wait
to see whether anyone  has a use case before adding more complexity.
