forward precise-flag if supported

Browse Source 
New versions of virglrenderer supports the precise-flag, so let's
forward it from TGSI if that's the case.

This fixes a few dEQP-GLES31 tests:
- dEQP-GLES31.functional.tessellation.common_edge.quads_equal_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.quads_fractional_even_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.quads_fractional_odd_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.triangles_equal_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.triangles_fractional_even_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.triangles_fractional_odd_spacing_precise
