Kernel: Fix incorrect flags for the GDT entries
...

Kernel: Add CPUID flag for long mode
...
This isn't particularly useful because by the time we've entered
init() the CPU had better support x86_64 anyway. However this shows the
CPU flag in System Monitor - even in 32-bit mode.

Kernel: Fix GDT limits
...
The GDT limits are inclusive, so for correctness we should subtract
one from the structs' size.

Kernel: Use proper Atomic<T> types in CPU
...
This is needed because Clang's intrinsic atomic functions behave weirdly
if only one of their pointer arguments is volatile.

Kernel: Add stubs for missing x86_64 functionality
...
This adds just enough stubs to make the kernel compile on x86_64. Obviously
it won't do anything useful - in fact it won't even attempt to boot because
Multiboot doesn't support ELF64 binaries - but it gets those compiler errors
out of the way so more progress can be made getting all the missing
functionality in place.
