wined3d: Avoid read-to-read resource barriers. 

Guard against the most recent write operation instead. Accumulate read
bindings to a) not issue unnecessary barriers when a resource has
multiple read-only usages, and b) synchronize with all previous read
bindings when writing.

This is motivated by an issue where a program using a single buffer to
store both indices and vertex attributes causes superfluous barriers on
each draw call.
