As reported in CVE-2024-13745 via oss-sec, DxeTpm2MeasureBootLib can
measure a partition table that differs from the one parsed by the
PartitionDxe driver.
To address this, the more complete GPT parsing logic from PartitionDxe
is extracted into a standalone GptLib library so it can be
shared between PartitionDxe and DxeTpm2MeasureBootLib. This ensures
that the exact same partition table measured into PCR[5] is the one
parsed and used by the system. PartitionDxe behavior is unchanged.
