Add support for tiled textures

[anarsoul]

We need to support tiled textures for performance reasons (they're faster to sample for GPU) and as a workaround for issue #53

[anarsoul]

Initial support lives in my branch: https://github.com/anarsoul/mesa-lima/tree/lima-18.0-tiled-textures

It currently has few issues:

1. Texture uploaded by memcpy-ing data to pointer returned by gbm_bo_map() is garbled - driver tries to use tiled textures when possible and apparently we don't support creating resources with modifiers yet.
2. Tiling/untiling is not optimized yet.

[anarsoul]

Rebased onto lima-18.1, not it lives in https://github.com/anarsoul/mesa-lima/tree/lima-18.1-tiled-textures

I've built and installed lima-18.1-tiled-textures on an amlogic s905x board, what should I use to test it?

[anarsoul]

@koenkooi for example you can sample from 500x500 texture. Try https://github.com/anarsoul/kmscube - it won't work without tiled textures

both 'kmscube-anarsoul' and 'kmscube-anarsoul -M rgba' show a spinning cube on the screen. Picture of the rgba one attached.

@koenkooi thanks for testing. It should also work with weston once we fix issue #59
