UefiPayloadPkg: Build a HOB from bootloader ACPI table

Browse Source 
V2: Update BuildHobFromAcpi() to return a HOB pointer.

For universal UEFI payload, build a HOB from the ACPI table, so that
other modules could use this info from HOB at very early DXE phase.
This code are shared by universal payload and non universal payload.
