Introduce convertRectsToMainFrameCoordinates for batching multiple rect
conversions
https://bugs.webkit.org/show_bug.cgi?id=311871
rdar://174446469
Reviewed by Aditya Keerthi.
convertRectToMainFrameCoordinates converts a single rect from a subframe's
coordinate space to the main frame via a recursive IPC chain (one round-trip
per frame level). Callers that need to convert multiple rects from the same
frame must make separate sequential calls, each incurring their own IPC
round-trips.
Introduce a batch variant `convertRectsToMainFrameCoordinates`that
converts a Vector<FloatRect> in a single IPC call per frame level. A new
ContentsToRootViewRects IPC message handles the WebProcess side by iterating
the vector through the existing contentsToRootView template.
No new tests, as this is not changing any functionality.
