Disable unsupported properties if qtForMCUs is set

When qtForMCUs is enable in the project, disables the action to open
the easing curve editor in the timeline and the actions to set an
interpolation to anything else than linear in the animation curve editor.
Shows the disabled reason in the tooltip and paint non linear curve
segments in the error color and without handles.
