kernel - Improve vm_page_register_action*() performance.

* Improve the performance for vm_page_register_action() and related
  routines by splitting the global lock into per-hash-index locks.
  Also change from a token to lockmgr locks.

* Shift some code around in umtx_sleep() so the tsleep_interlock()
  occurs after the registration code to avoid interference with
  the new lockmgr() operations in the registration code.
