lib/igt_vc4: Add helpers for converting linear to SAND-tiled buffers

In order to test buffers with SAND tiling, it is useful to convert
linear buffers to SAND tiling mode.

Introduce helpers to assist in that direction, one that calculates the
memory offset in the SAND-tiled buffer for a given pixel position and
one that makes use of the latter for framebuffer conversion.
