Fix #29369: bpy.data.curves.new(name= "test" , type = 'SURFACE') does not create a surface

This issue it totally related on issue with changing object datablock.
For curves it used to guess object type from curve datablock based on
count of control points in V direction.
This quess fails in case when SurfCircle datablock is trying to be reused
by another surface object or as another sample empty surface databouck used
to be treated as curve.

Store type in Curve when creating new Curve datablock which is used in
this object type quessing function.

Note: Previously saved files wouldn't change behavior at all.
