System Information
Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.68

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-08-26 20:00, hash: 2b64b4d90d
Worked: (newest version of Blender that worked as expected)

Short description of error
When using the Curve to Mesh node sometime the Profile Curve needs to be reversed for normals to face outwards.
Surely the node should automatically output faces pointing out?
Reversed normals is the default behaviour when using the curve primitive as the profile.

Exact steps for others to reproduce the error
Add a curve. Add a Curve to Mesh node. Add a circle curve primitive, and use it as the profile. Inspect face orientation.

Heh, I thought I fixed this in my commit closing #89687, but apparently I didn't think it through so well. It will depend on the direction of the primitive, so when I fixed it for the star node I guess I broke it for the circle node.

It's probably best to revert that and instead fix the direction of the star primitive (and any other cyclic circle primitive).
