Move page table allocation to top 256GiB.
...
I forgot to account for tracking page table physical addresses, so
this is a bit of an overhaul. Major changes:
- Refactor bootstrap code into more functions and:
- Only allocate 32 pages of scratch space
- Remap remaining space into top 256GiB, the "page table space"
- Use the page table space to directly offset-map page table pages
from their physical addresses, to avoid tracking overhead.
- Refactor page_block list functions into static functions to better
handle null/empty lists

Initialize page_manager.
...
Page manager now:
- Caches mapped pages and page_block structs
- Can unmap memory ranges
- Unmaps extra kernel memory during it's init

Finish memory bootstrap sequence.
...
Now we're setting up all our own page tables, and handing off to
page_manager's init function. (Which is still NYI.)

Rearrange memory manager into two classes.
...
page_manager and memory_manager are now separate, and are also pre
allocated in the kernel so they don't have to allocate themselves.

Refactor memory code.
...
Break out some more bootstrap code into functions. Add the start of
some Doxygen doc comments to help organize my thoughts.

Rearrange memory bootstrapping code.
...
Move EFI-related code and initial memory manager bootstrap code
to memory_bootstrap.cpp, move memory page structs to their own
memory_page.h/cpp files.

Move kernel to higher half.
...
Return to having the bootloader re-map the kernel into the higher
half before jumping into the kernel entrypoint, so we don't have
to juggle pointers inside the kernel.
