crosvm: align pmem region size to 2MiB
Linux commit 7ea6216049ff9cf250a6722cd766d99c8d1424e5 "mm/sparsemem: prepare for sub-section ranges" added validation of memory region sizes for hotplugging. This requires alignment of the region to 2MiB, which can be done with a MemoryMappingArena that will pad the end of the region with read-only pages.
