This rescales the whole scene by its root transform to match the same
visual size while not forcing the user to wait for scale to be applied to
each object.
This is requested by studios whose main applications / USD scenes are
in CM, because referencing and payloading scenes from disparate scales
can cause issues at resolution time.
If "Apply Unit Scale Conversion" is unchecked on import, the user now
has the ability to bring the objects in with a scale factor of 1.0, so that the
objects may be edited as if Blender's scene units matches the imported
stage's.
At export time, a "Stage Meters Per Unit" value can be chosen from a list
of common measurements, as well as setting a custom value.
