util/amdfwtool: Introduce support for Hash Table v2
Some stages in bootflow prefer to use 16 bytes UUID instead of
traditional 2 bytes FWID to identify the firmware components they
verify/validate. Hence add version 2 of hash table which identifies
firmware components using UUID. Other than UUID and a reserved field for
alignment reasons, the format of the hash table is very similar to hash
table v1.
BUG=b:277292697
TEST=Build and boot to OS in Myst with PSP Verstage enabled. Ensure that
the hash table v2 is built and installed into BIOS image for the
components that are configured in amdfw.cfg file. Ensure that the
validation by PSP is successful for all the relevant components during
the boot flow.
