Move dataURL creation in tabsCaptureVisibleTab to background thread
https://bugs.webkit.org/show_bug.cgi?id=308776
rdar://170628256
Reviewed by Timothy Hatcher.
A significant number of MobileSafari hangs in telemetry are coming from the
creation of the data url
for the snapshotted tab in WebExtensionContext::tabsCaptureVisibleTab. Creating
the data URL
involves both encoding the snapshot as a PNG and turning it in to a data URL on
the main thread.
Move this work to a background thread instead.
