Add a new boolean input to the curve to mesh node: "Fill Caps"

Caps should only be added for cyclic profiles.
The caps should be N-gons.
- More complicated meshes for caps are theoretically possible, but performance is very important for this node, since it's a basic piece of the curve workflow, so that should be considered later.
The caps should share the existing edges at the first and last profile.
The edges of the caps should be marked sharp.

In terms of design, it may worth considering making this an enum instead of a boolean input, so that a "round caps" option could be more simply added later (avoiding options that depend on each other). However, for testing and an initial patch, it could simply be a boolean input.

Mesh to Curve? Or Curve to Mesh?

Looks like one of the caps gets flipped normals.
