Add a quaternion rotation socket type, and using the recently added
rotation attribute type, support the type in most of the multi-type
geometry nodes, and modifier attribute inputs and outputs.

The socket is still exposed with an XYZ Euler default value.
In the future we can add modes to this rotation value similar
to object rotations.

Rotation values have no implicit conversions to other types.
Nodes to convert to and from rotation values will be added
in a follow-up commit.

For now, the new socket type is hidden behind and experimental
option, because we haven't chosen the final color for it yet.

Looks good, this will help a lot. Some field dependencies probably need corrected indices.

I would like to have a "raw" xyzw component mode here. All other vector-like types support that. The euler and axis-angle modes may be more intuitive, but there are situations where i would want direct access to these values. Example: hair simulation models based on elastic rods require the imaginary part of a quaternion product. The combine node can do normalization implicitly.

Great point! The RNA for these new nodes wasn't meant to be in this patch actually, but I'll remember that for the next one that introduces these nodes.

The code looks good, but unsure if we can merge this without picking the color first. If adding the experimental option takes less than 30 min, I think it's worth it.

Fairly simple, this is my commit adding an experimental flag for the panels 066d40b7b5
