Kernel: Add fast page to page table
...
Add "fast page" to KERNEL_OFFSET. This is always present in page
tables and only requires changing the page table entry to map. This
requires no interrupts since it should only be for very operations
like memcpy.
I used to map all temporary mappings to vaddr 0, but this is much
better. C++ standard always says that nullptr access is undefined
and this gets rid of it.
Fixed some bugs I found along the way

This allows String to shrink by 8 bytes since Variant's 8 index is

This required me to make Strings max size one bit less, but that
should still be fine. There should never be strings with size of
over half of the computer's address space.
