[mtl canvas] Fix artifacts on tiger that was due to epsilon comparison for cubics equation in draw kernel. Removed that (now do <= 0), but then we need to weed out false negatives for solid triangles. So we compute if the triangle is solid in the triangle kernel and store it in the mg_triangle_data struct for now.

[mtl canvas] adding a color command for fully covered, solid color tiles. This is not much of an improvement for now because the tile array just got bigger, but maybe we can use the same scheme and compact it into an int

[mtl canvas] bucket triangles into per-shape tile queues, then gather into tile arrays. This somewhat improves perf for perf_text test and avoids an awful degradation due to sorting in tiger test (tiger now runs at ~20fps, which is still much slower than it could be, but the triangle coverage method we're using just incurs too much cross product computations...)

[mtl surface] fix crash on exit when metal GPU frame capture is enabled. Apparently, if we release resources (on exit) before all GPU work is completed, libMetalCapture crashes on bad access. To work around that, in mg_mtl_surface_destroy(), we enqueue a last (empty) command buffer and call waitUntilCompleted on it, to ensure all previous command buffers are also completed
