[release/10.0] Fix Clipboard.GetDataObject().GetImage regression for bitmap images

[github-actions]

Fixes #14423

main branch commit #14427

Description/Customer Impact

In .NET 10/11, it is not possible to use Clipboard.GetDataObject().GetImage() API to retrieve images from the Clipboard. This API returns null.

Root cause

In .NET 10, Clipboard was updated to use the new typed + NRBF pipeline. In this new approach, bitmap images are stored mainly in the ITypedDataObject typed store, but DataObject.GetImage still reads from the legacy GetData store and hence the Clipboard.GetDataObject().GetImage() can no longer see those images on .NET 10/11 and returns null.

Fix

Updated DataObject.GetImage() API to use TryGetData<Image>(DataFormats.Bitmap, autoConvert: true, out image) which returns image using the new typed/NRBF code.

Regression

Regression from .NET 9.0. Introduced by commit #11545

Risk

Very low. Another public API, Clipboard.GetImage() already uses TryGetData<T> API and is working fine.

Testing

Manual testing and added unit test for this scenario
