Kernel: Simplify scanning BIOS/EBDA and MP parser initialization

Add a MappedROM::find_chunk_starting_with() helper since that's a very
common usage pattern in clients of this code.

Also convert MultiProcessorParser from a persistent singleton object
to a temporary object constructed via a failable factory function.

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.
