pmap & buffer cache dummy pagers

Diff below introduces two dummy pagers for subsystem that manipulate UVM objects that are 'special'. Those pagers will be used to enforce checks in functions that expect a lock to be held, like: KASSERT(obj == NULL || UVM_OBJ_IS_PMAP(obj) || rw_write_held(obj->vmobjlock));
