Display pipeline performance, PAT write-combining support

* Program x86 PAT MSR and remap framebuffer as write-combining
  in both UEFI and BIOS boot paths to eliminate screen tearing
* Add flags parameter to arch_phys_map (PHYS_MAP_WC) for portable
  cache-mode selection, update all callsites
* Add per-window dirty tracking in window server; WM redraws only
  on content changes, notify WM on virtual screen switch
* Batch PTY reads with O_NONBLOCK, optimize terminal scroll with
  pixel memmove, single pread for WM window blitting
* Optimize draw_fill_rect with memset/memcpy fast paths, remove
  _reap_dead_owners from hot I/O paths
