Map the vm_page array into KVA on amd64.

r351198 allows the kernel to use domain-local memory to back the vm_page
array (up to 2MB boundaries) and reserves a separate PML4 entry for that
purpose.  One consequence of that change is that the vm_page array is no
longer present in minidumps, which only adds pages mapped above
VM_MIN_KERNEL_ADDRESS.

To avoid the friction caused by having kernel data structures mapped
below VM_MIN_KERNEL_ADDRESS, map the vm_page array starting at
VM_MIN_KERNEL_ADDRESS instead of using a dedicated PML4 entry.
