Update Spratly Spat platforms to new Water-Surface facilities

[cmanouser1]

The Chinese platforms in Spratly Spat should be changed to the new water-surface facilities type rather than the deprecated ship-platform type.
This will allow targeting by the tomahawks.

(v1.06.1328.13 added water-surface facilities [(supported only on v504+ DBs). Such facilities are
placed on the water surface (not on the sea bottom) and can be attacked with both land-attack
and anti-ship weapons. Examples of such facilities include bridges (both single-unit and multi-
segment), offshore platforms, piers etc.])
