Chris Bracken 49e25a2dee [macOS] Top-left origin for PlatformView container (flutter/engine#42523) ...

For consistency with Flutter (and all other platforms), Flutter views in the macOS embedder set `isFlipped` to ensure a co-ordinate system with the origin in the top-left, with y co-ordinates increasing towards the bottom edge of the view.

Previously, we were using a stock NSView as the container, which uses a bottom-left origin by default. Instead we extract the PlatformView container view as its own class with `isFlipped` true.

This doesn't correct the issue of the view anchorpoint/position but does correct rotation direction.

This also applies the transform back to origin prior to other transforms when adjusting the platformview position rather than after.
