Victor Sun 97e52fe12b HV: boot guest with boot params ...

Previously the load GPA of LaaG boot params like zeropage/cmdline and
initgdt are all hard-coded, this would bring potential LaaG boot issues.

The patch will try to fix this issue by finding a 32KB load_params memory
block for LaaG to store these guest boot params.

For other guest with raw image, in general only vgdt need to be cared of so
the load_params will be put at 0x800 since it is a common place that most
guests won't touch for entering protected mode.

Tracked-On: #5626
