etnaviv: Add sampler TS support

Graphics / Mesa 3D Graphics Library / Mesa - Wladimir J. van der Laan [] - 15 November 2017 22:27 EST

Sampler TS is an hardware optimization that can be used when rendering to textures. After rendering to a resource with TS enabled, the texture unit can use this to bypass lookups to empty tiles. This also means a resolve-in-place can be avoided to flush the TS.

This commit is also an optimization when not using sampler TS, as resolve-in-place will now be skipped if a resource has no (valid) TS.
