tract.c -- fix more ChunkCache defects:
- drop never-read chunkCache->pageTableBase and pageTableLimit fields: they were used for ChunkOfSeg(), back when each SegStruct was actually a PageStruct is some chunk's PageStructTable; see VMArenaChunkOfSeg() in //info.ravenbrook.com/project/mps/branch/2001-08-13/trunk/src/arenavm.chttps://github.com/Ravenbrook/mps/issues/46
- there's no need for arena to initialise the chunk cache; this allows en/decache functions to be local to tract.c (ie. declared static)
