renderer: Fix mirrored displays when transformed and preserve aspect ratio (#5697)

* renderer: transform mirror buffer and preserve mirror aspect ratio

* renderer: render mirrors directly from offloadFB

* renderer: fix formatting

* renderer: use monitorMirrorFB again, but properly damage mirrors

* renderer: clean mirrors after reload and support cursor zoom mirroring
