Geometry Nodes: new Attribute Sample Texture node

This node allows sampling a texture for every vertex based on some
mapping attribute. Typical attribute names are the name of a uv map
(e.g. "UVMap") and "position". However, every attribute that can be
converted to a vector implicitly is supported.

It should be noted that as of right now, uv map attributes can only be
accessed after a Point Distribute node.
