Andreas Kling 84b7bc5e14 Kernel: Add convenient ways to map whole BIOS and EBDA into memory ...

This patch adds a MappedROM abstraction to the Kernel VM subsystem.
It's basically the read-only byte buffer equivalent of a TypedMapping.

We use this in the ACPI and MP table parsers to scan for interesting
stuff in low memory instead of doing a bunch of address arithmetic.
