Don't generate events from wxSpinCtrl::SetRange() in wxMSW.

Other ports don't send wxEVT_COMMAND_SPINCTRL_UPDATED from SetRange() even if
the value changed because it was adjusted to fit into the new range and this
makes sense as this change is not due to a user action, so don't send this
event under wxMSW neither.

Also add a unit test checking for this behaviour.

Closes #14583.
