HV: add e820 ACPI entry for pre-launched VM

Browse Source 
Previously the ACPI table was stored in F segment which might not be big
enough for a customized ACPI table, hence reserve 1MB space in pre-launched
VM e820 table to store the ACPI related data:

	0x7ff00000 ~ 0x7ffeffff : ACPI Reclaim memory
	0x7fff0000 ~ 0x7fffffff : ACPI NVS memory

Tracked-On: #5266
