Curves: Port set type node to new data-block

This commit ports the "Set Spline Type" node to the new curves type.
Performance should be improved in similar ways to the other refactors
from the conversion task (T95443). Converting to and from Catmull Rom
curves is now supported. There are a few cases where a lot of work can
be skipped: when the number of points doesn't change, and when the
types already match the goal type.

The refactor has a few other explicit goals as well:
 - Don't count on initialization of attribute arrays when they are
   first allocated.
 - Avoid copying the entire data-block when possible.
 - Make decisions about which attributes to copy when changing curves
   more obvious.
 - Use higher-level methods to copy data between curve points.
 - Optimize for the common cases of single types and full selections.
 - Process selected curves of the same types in the same loop.

The Bezier to NURBS conversion is written by Piotr Makal (@pmakal).
