x86/boot: Parse SRAT table and count immovable memory regions
Parse SRAT for the immovable memory regions and use that information to
control which offset KASLR selects so that it doesn't overlap with any
movable region.
[ bp:
- Move struct mem_vector where it is visible so that it builds.
- Correct comments.
- Rewrite commit message.
