Magic action drawable with turbulence and sparkles

Drawable implementation using RuntimeShader.
Base shaders come from sysui-shader-lib, combining simplex3d and
triangle noise.

The button is currently static, but was designed in a way where it's
possible to support animations by incrementing the `seed` parameter.
