tu: Clear viewport dirty state with static viewports

Vulkan allows the user to set extraneous dynamic state which then gets
ignored if a pipeline with static state is bound. We weren't
implementing this correctly for viewports because we weren't clearing
the dirty bit, but it was happening to work until changes for dynamic
depth negative-one-to-one broke
