turnip: Don't use the dynamic color write enable during non-dynamic.

Browse Source 
We have the correct merged color write enable state as a local var here,
use that instead of the zero cmd->state.color_write_enable.  Fixes
blending in many traces with ANGLE on turnip.  In the process of fixing,
clarify the logic a little bit.

Fixes: 169e03800d ("tu: Implement VK_EXT_color_write_enable")
Fixes: #7328
