RH-Commit: [8/10] 9ae7e900f38bfa95694841b68520560e02b0f927 (kraxel.rh/centos-src-edk2)
Loop over all MP_HAND_OFF HOBs instead of expecting a single HOB
covering all CPUs in the system.
Add a new FirstMpHandOff variable, which caches the first HOB body for
faster lookups. It is also used to check whenever MP_HAND_OFF HOBs are
present. Using the MpHandOff pointer for that does not work any more
because the variable will be NULL at the end of HOB loops.

Rename the function to GetNextMpHandOffHob(), add MP_HAND_OFF parameter.
When called with NULL pointer return the body of the first HOB, otherwise
return the next in the chain.
Also add the function prototype to the MpLib.h header file.
