Subject: Geometry Nodes: Add preferred domain to many field inputs

The preferred domain is used to decide which domain the viewer node
should use when set to "Auto" domain. This commit adds it to some curve
input nodes and the curve and mesh topology nodes. This makes debugging
node setups with these nodes a bit faster and less frustrating.
