vc4: Initial skeleton driver import.
This mostly just takes every draw call and turns it into a sequence of commands that clear the FBO and draw a single shaded triangle to it, regardless of the actual input vertices or shaders. I copied the initial driver skeleton mostly from freedreno, and I've preserved Rob Clark's copyright for those. I also based my initial hardcoded shaders and command lists on Scott Mansell (phire)'s "hackdriver" project, though the bit patterns of the shaders emitted end up being different. v2: Rebase on gallium megadrivers changes. v3: Rebase on PIPE_SHADER_CAP_MAX_CONSTS change. v4: Rely on simpenrose actually being installed when building for simulation. v5: Add more header duplicate-include guards. v6: Apply Emil's review (protection against vc4 sim and ilo at the same time, and dropping the dricommon drm bits) and fix a copyright header (thanks, Roland)
