x86: support up to 16Tb
This mainly involves adjusting the number of L4 entries needing copying
between page tables (which is now different between PV and HVM/idle
domains), and changing the cutoff point and method when more than the
supported amount of memory is found in a system.
Since TMEM doesn't currently cope with the full 1:1 map not always
being visible, it gets forcefully disabled in that case.
