Tile rendering reorganization
...
This significantly simplifies the dispatch process by creating a
proper backing store for the tiles. Most values that were
calcualted on the fly are now stored as constants in the tile
store.
Also, all tile updated are run through the dirty tile list which
solved a checken-and-egg problem of which order to do sprites vs
new tiles and affords a lot of optimizations since tile rendering
is deferred and each tile is only drawn at most once per frame.

Complete masked tile rendering implementation

The core data tables were reworked to pre-reverse all of the
entries to directly match the right-to-left ordering of the code
fields. This simplified some code but was required for register
reuse in the masked tile renderer.
Also fixed several offset calculation issues in the masked tile
renderer.

Fix tile rendering
...
This is not quite correct yet. IT appears that two rows or columns are
drawn on the edges when only a single solumn or row is necessary. Also,
this code is based on the old GTE codebase, so the initial rectangle for
rendering tiles is width+1, height+1. This can be improved.
