EmbeddedPkg/Scripts/LauterbachT32: Fix EfiLoadDxe.cmm

Browse Source 
There have been many changes since EfiLoadDxe.cmm was last updated in
2011. The EFI_SYSTEM_TABLE can no longer be found by scanning memory on
4KB boundaries, so require users pass in its address instead. Update
various offsets so that the debug information can be found and loaded
with a recent version of TRACE32.
