Instead of associating a single PCID with each set of page tables (which
will reach the maximum quickly), allow a dynamic pool for each vCPU.
This is the same way that Linux operates. We also split management of
PCIDs out of the page tables themselves for simplicity.

In order to prevent possible garbage collection and reuse of page table
pages prior to invalidation, introduce a former allocator abstraction
that can ensure entries are held during a single traversal. This also
cleans up the abstraction and splits it out of the machine itself.

This is a refactor of ring0 and ring0/pagetables that changes from
individual arguments to opts structures. This should involve no
functional changes, but sets the stage for subsequent changes.

Especially in situations with small numbers of vCPUs, the existing
system resulted in excessive thrashing. Now, execution contexts
co-ordinate as smoothly as they can to share a small number of cores.
