cdab5b2091 Kernel: Make identity mapping mechanism used during AP boot non-generic 
When booting AP's, we identity map a region at 0x8000 while doing the
initial bringup sequence. This is the only thing in the kernel that
requires an identity mapping, yet we had a bunch of generic API's and a
dedicated VirtualRangeAllocator in every PageDirectory for this purpose.

This patch simplifies the situation by moving the identity mapping logic
to the AP boot code and removing the generic API's.

cd5faf4e42 Kernel: Rename Range => VirtualRange 
...and also RangeAllocator => VirtualRangeAllocator.

This clarifies that the ranges we're dealing with are *virtual* memory
ranges and not anything else.

a1d7ebf85a Kernel: Rename Kernel/VM/ to Kernel/Memory/ 
This directory isn't just about virtual memory, it's about all kinds
of memory management.
