Fix some more uvm.h cleanup fallout.

Round of uvm.h cleanup.

The poorly named uvm.h is generally supposed to be for uvm-internal
users only.

- Narrow it to files that actually need it -- mostly files that need
  to query whether curlwp is the pagedaemon, which should maybe be
  exposed by an external header.

- Use uvm_extern.h where feasible and uvm_*.h for things not exposed
  by it.  We should split up uvm_extern.h but this will serve for now
  to reduce the uvm.h dependencies.

- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use
  UVMHIST(ubchist), since ubchist is declared in uvm.h but the
  reference evaporates if UVMHIST is not defined, so we reduce header
  file dependencies.

- Make uvm_device.h and uvm_swap.h independently includable while
  here.
