Don't use default RTTI for these since they are performance-sensitive.

UserspaceEmulator: Convert backing storage from malloc to mmap
...
This saves a few bytes for each guest-mmaped region, especially since these are likely to be page-aligned.

UserspaceEmulator: Implement a proper VM allocator
...
This patch brings Kernel::RangeAllocator to UserspaceEmulator in a
slightly simplified form.
It supports the basic three allocation types needed by virt$mmap():
allocate_anywhere, allocate_specific, and allocate_randomized.
Porting virt$mmap() and virt$munmap() to use the allocator makes
UE work correctly once again. :^)
