Kernel: Fix GDT and segment selectors to make userland work on x86_64
...
Userland faulted on the very first instruction before because the
PML4T/PDPT/etc. weren't marked as user-accessible. For some reason
x86 doesn't care about that.
Also, we need to provide an appropriate userspace stack segment
selector to iretq.

Kernel: Fix stack for new threads on x86_64

Unlike on x86 iretq always pops rsp and ss.

Kernel: Rename Thread::tss to Thread::regs and add x86_64 support
...
We're using software context switches so calling this struct tss is
somewhat misleading.

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.
