Rework logic for skipping .depend/.meta file read/stat/writes.

- Rename _SKIP_READ_DEPEND to _SKIP_DEPEND since it also avoids writing.
- This now uses .NOMETA to avoid reading any .meta files related to
  DEPENDOBJS.  Objects not in OBJS/DEPENDOBJS may still have their .meta
  files read in if they are in the dependency graph.
- This also avoids statting .meta and .depend files in the META_MODE +
  -DNO_FILEMON case.
