x86, mm: Move CR3 construction functions
For flushing the TLB, we need to know which ASID has been programmed
into the hardware. Since that differs from what is in 'cpu_tlbstate',
we need to be able to transform the ASID in cpu_tlbstate to the one
programmed into the hardware.
It's not easy to include mmu_context.h into tlbflush.h, so just move
the CR3 building over to tlbflush.h.
