Replace usages of new Image(device, width, height) with new GC(image, style)

[ShahzaibIbrahim]

GC can be initialize with GC(drawable) or GC(drawable, style). Currently Image(Device, ImageGcDrawer, height, width) doesn't consider style attribute while initializing GC. We need to create a new constructor for Image. e.g. Image(Device, ImageGcDrawer, height, width, style) for which later GC inside ImageGcDrawer is initialized considering the style provided to it.

Here is the example for simple rectangle with and without styling providing (RIGHT_TO_LEFT in this case)

What about extending the ImageGcDrawer interface with a getGcStyle() method having a default implementation returning SWT.None? Then one could pass this information via the drawer implementation. In my opinion, it would make even more sense as the information is related to the GC-drawing process than the image.
@akoch-yatta @ShahzaibIbrahim wdyt?

Oh yeah, that is a really simple but great idea. And it just makes so much sense. I am a bit annoyed I didn't come up with it 😄

Sounds good to me, I will do it first in a separate PR to accommodate styling. Replacing the calls in another.
