tcgbios: Measure the GPT table
Measure and log the GPT table including LBA1 and all GPT table entries
with a non-zero Type GUID.
We follow the specification "TCG PC Client Platform Firmware Profile
Specification" for the format of what needs to be logged and measured.
See section "Event Logging" subsection "Measuring UEFI Variables" for
the UEFI_GPT_DATA structure.
