turnip: make tiling config part of framebuffer state

Compute the tiling config at framebuffer creation time. A framebuffer will b
be re-used multiple times, so this will avoid having to re-calculate the
tiling config every time a command buffer is recorded.

The tiling config already couldn't use the render area's x1/y1 because of
hw binning, this move makes it so the render area isn't used at all for the
tiling config.
