Split ExtractedWindows into entities and respective components #7098
Description
What problem does this solve or what need does it fill?
With the Window as Entities PR, @inodentry brought up a good point related to the extraction code for windows: #5589 (comment)
What solution would you like?
Have the extraction code copy over the Window component as well as having an ExtractedWindow component that would have the swap frame/other rendering specific details in it.
What alternative(s) have you considered?
Leaving it as is, but this seems like a good code quality improvement.
