Implementation of Image to enable Multi Zoom Level Support for Win32

[amartya4256]

Issues: https://github.com/eclipse-platform/eclipse.platform.swt/issues/62 and https://github.com/eclipse-platform/eclipse.platform.swt/issues/131

This pull request is based on the implementations of PR #1214. It extends to the native zoom which is provided within widget and propagated to GC. In this PR, we provide a map of different handles to Image for different device zoom levels as required by different monitors. The method win32_getHandle provides the appropriate handle for the scaled image as per requested by the client. The clients avail the zoom level information from the GCData and Widget (based on PR #1214 ).

Note: Only the last commit is the relevant commit because it is based on the PR #1214. Must be merged after #1214 has been merged.

Fixed the issue with the icon of the shell. But I have also created a follow up issue which addresses the problem in the depth but it doesn't have to be the part of this PR because it addresses the usability of a method outside its scope. https://github.com/orgs/vi-eclipse/projects/1/views/1?filterQuery=assignee%3Aamartya4256+47&pane=issue&itemId=67443386 FYI @akoch-yatta @fedejeanne @HeikoKlare
