DeveloperBox: implement measured boot

Enable the various components, library class resolutions and PCD defaults
to enable measured boot based on a version 2 TPM. The TPM is exposed as
having a memory mapped TIS frame, which is accomplished using the SPI
command sequencer that is available on this platform. Note that this
requires SCP firmware support.
