svga: Implement the pipe clear_render_target functionality v2

Graphics / Mesa 3D Graphics Library / Mesa - Thomas Hellstrom [vmware.com] - 3 November 2016 15:29 UTC

v2: Accounted for the fact that svga_try_clear_render_target also honors conditional rendering.

Testing done: Excercised all functions in a separate feature branch. Forced emission of conditional rendering commands when necessary.
