RFR: 8364547: Window size may be incorrect when constrained to min or max [v3]

[Martin Fox]

> When changing the width and height of a window the platform code is responsible for enforcing the min and max size constraints. If the final width and height don't match the width and height passed into setBounds the platform needs to call notifyResize to correct the window's properties. This happens naturally if the window size actually changes since that will trigger the OS to send size change notifications. If the platform window size doesn't change the OS notifications won't trigger. We need to catch that case and send notifyResize anyway.

> This PR does this for Mac and Windows. Linux is being handled in PR #1789 which also includes the system tests for these bugs.

 - If min/max window size enforced send notification to correct Window properties
 - Merge remote-tracking branch 'upstream/master' into sendcorrectsize
 - Comment cleanup
 - Notify WindowStage if setBounds didn't change the size as expected
