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.
