  [#23108] bpy.ops.object.origin_set(type='GEOMETRY_ORIGIN') dosen't work in console
  [#23115] Crash when moving armature origin

- setting the armature in editmode would leave editdata in some cases.
- transforming selected linked objects to account for the movement of the obdata was only done for meshes, now do for curves and text3d.
- added utility functions for getting curve & mesh bounds.
- text3d moving center wasn't working at all.
- changed drawobject.c to use BLI_math funcs in more places.
- remove some unused code from operator object.origin_set.
