Add a helper to allocate a page for use in constructing the guest's page
tables. All architectures have identical address and memslot
requirements (which appear to be arbitrary anyways).
No functional change intended.

Drop the memslot param from virt_pg_map() and virt_map() and shove the
hardcoded '0' down to the vm_phy_page_alloc() calls.

Drop the memslot param(s) from vm_vaddr_alloc() now that all callers
directly specific '0' as the memslot. Drop the memslot param from
virt_pgd_alloc() as well since vm_vaddr_alloc() is its only user.
I.e. shove the hardcoded '0' down to the vm_phy_pages_alloc() calls.
No functional change intended.

Move function documentation comment blocks to the header files in
order to avoid duplicating them for each architecture. While at
it clean up and fix up the comment blocks.

Currently vcpu_args_set is only implemented for x86. This makes writing
tests with multiple vCPUs difficult as each guest vCPU must either a.)
do the same thing or b.) derive some kind of unique token from it's
registers or the architecture. To simplify the process of writing tests
with multiple vCPUs for s390 and aarch64, add set args functions for
those architectures.
