gpu: debug-print the used shader clip

When using GSK_DEBUG=verbose, print the clip mode used in the shader.
Use cute little unicode indicators to not overload the debug output.

gpu: Setup attribute locations
...
Make the generator generate calls for the correct glBindAttribLocation()
calls.
Usually this was done correctly, but we can't rely on it. So do it
explicitly.

gpu: Introduce the concept of "variation"
...
A variation is a #define/specialization constant that every shader can
use to specialize itself as it sees fit.
This commit adds the infrastrcture, future commits will add
implementations.

gpu: Optimize box-shadow shader

gpu: Add a box shadow shader
...
Code was inspired mainly by
https://madebyevan.com/shaders/fast-rounded-rectangle-shadows/
and
https://pcwalton.github.io/_posts/2015-12-21-drawing-css-box-shadows-in-webrender.html
So far the results aren't cached, that's the task of future commits.
