This increases the preallocation sizes for UEFI runtime services code
and data regions. This does not actually affect the footprint, but it
reserves memory zones early on so that all allocations of each type
can be served from adjacent regions.

With this patch applied, we end up with fewer entries in the memory map,
resulting in more efficient page tables due to the lower fragmentation.
