Fix HiDPI progress icon clipping by relayouting only on image size change

On Windows HiDPI screens, the progress icon in the status bar could appear clipped because Toolbars are initially created  by windows with default button size (24×22). When larger images are set (e.g., 32×32 for 200% scaling), the toolbar resizes but the parent layout isn't updated due to deferred layout. This change adds a check to determine if the image size actually changed before requesting a relayout. The parent layout is now updated only when necessary, matching SWT's behavior for toolbar images and preventing unnecessary layouts while fixing the clipping issue.
