Non system cursors adaption to DPI scale changes

[ShahzaibIbrahim]

Creating a map to provide different handle w.r.t the current zoom of the display. The method win32_getHandle provides the appropriate handle for the scaled image as per requested by the client.

HOW TO TEST

• Run the Snippet92 (Image) or Snippet119 (Icon) with the following VM Arguments

-Dswt.autoScale=quarter
-Dswt.autoScale.updateOnRuntime=true

• Run the example
• Move the mouse pointer to the window
• See if the mouse pointer is scaled to the current monitor zoom level.
• Now move the window to another monitor with different zoom level (i.e. 200%)
• Move the mouse pointer to the window again
• See if the pointer still scaled correctly according to 200% zoom level

I didn't test this, I only have some proposals regarding the coding style and JavaDoc.

I also have 2 questions regarding returning a handle of a cursor that is already disposed and about making the field handle private.

[fedejeanne]

Changes look good, they produce the expected result and I see no regressions either.

Please remove the extra (unnecessary) call to registerResourceWithZoomSupport(this) from the constructor, squash and rebase your commits and then this PR is good to go ✔️
