tiles.rc: remove 'description' annotation for undefined/unused tiles

The earlier commit that added the description annotations maintained
exact compatibility with the descriptions hardcoded in the source
code. Now we are going back and removing the descriptions that do
not apply.

tile descriptions: consolidate to a single string for 'draw bridge'

formerly, the string "Draw Bridge" was defined separately for
east-west and north-south bridges, simply because they were disjoint
in the tile numbering sequence.

Now both draw bridges use description number 20.
This frees up description number 25 for something else some day.

tile descriptions: smoke on coal power plant should be "Coal Power" not "Industrial"

remove description annotation on the animated tiles of the coal power plant,
so that they inherit the description of the coal power plant, rather than
having a description of "Industrial"

tile descriptions: describe the animated zone destruction tiles as "Rubble"

rather than "Industrial"

tile descriptions: consolidate to single string for 'Industrial'

Formerly #23 and #12 were both "Industrial", with #12 being used for
the basic industrial zones, and #23 being used for any animation
appearing for industrial zones.

Now that the tiles using a particular description number don't need
to be contiguous, we will consolidate to just use #12 for "industrial",
and this will free up #23 for some other use in the future.
