Subject: IMP: Delete the memory list when exiting process. IMP: Add Allocation
 (and delete) of MemoryList. IMP: BitMap allocator must now allocate
 directories as well. IMP: Add Handover arch to check if executable is an
 AMD64 executable or ARM64 executable. FIX: Add ::EFI::Stop, when a thread
 doesn't load correctly.
