intel/fs: disable VRS when omask is written 

As indicated by
VkPhysicalDeviceFragmentShadingRatePropertiesKHR::fragmentShadingRateWithShaderSampleMask
our implementation will clamp to 1x1 when reading samplemask or
writing to samplemask.

This fixes vkd3d-proton tests test_sample_mask_dxbc & test_sample_mask_dxil
