wined3d: Add extension information to the states.

This patch adds a new field to the state templates. If this extension field is != 0, then the line is only applied to the final state table if the extension is supported. Once a line is applied to the final table, all further templates for this state from the same pipeline part are ignored. This allows removing some extension checks from the state handlers, which cleans them up and saves a few CPU cycles when applying the states.

wined3d: Add extension information to the states.
