Geometry Nodes: Fields version of Curve to Points node

This commit adds an updated version of the curve to points that
supports fields. Only the position and radius are transferred
by default now, which should improve performance. The other outputs
like tangent and rotation are outputted with anonymous attributes.

I took the opportunity to change a few other small things:

 - Name geometry sockets "Curve" and "Points" like other nodes.
 - Remove the radius multiple of 0.1, which was confusing.

Thanks to @Johnny Matthews (guitargeek) for an initial patch.
