vrend: do not overwrite a sampler-object that might be in use

Browse Source 
When we set the srgb-decode state, we might overwrite another
incompatible usage of the same sampler object.

To avoid this, create two sampler-objects, one for the decode-state
and one for the skip-decode state.

This fixes the following dEQP-tests on GLES:
- dEQP-GLES31.functional.srgb_texture_decode.skip_decode.srgba8.conversion_gpu
- dEQP-GLES31.functional.srgb_texture_decode.skip_decode.srgba8.toggled
- dEQP-GLES31.functional.srgb_texture_decode.skip_decode.srgba8.multiple_textures
