OvmfPkg/PlatformInitLib: Add PlatformGetLowMemoryCB
Add PlatformGetLowMemoryCB() callback function for use with
PlatformScanE820(). It stores the low memory size in
PlatformInfoHob->LowMemory. This replaces calls to
PlatformScanOrAdd64BitE820Ram() with non-NULL LowMemory.
Write any actions done (setting LowMemory) to the firmware log
with INFO loglevel.
Also change PlatformGetSystemMemorySizeBelow4gb() to likewise set
PlatformInfoHob->LowMemory instead of returning the value. Update
all Callers to the new convention.
