Disable local space for blender transforms.

Having local_space enabled when starting a transform changed the
behavior of VIEW space transforms. Now we disable local_space when
starting a blender transform (there was already logic to restore the
setting after the transform ends).

This also hides the gizmo while performing a blender transform,
otherwise the user will see it snap back and forth between the local and
global alignment. I think the transform looks cleaner with the gizmo
hidden anyways.

Fixes #59392.
