fix(macOS): use transform3D in Fabric component views

Use self.transform3D instead of self.layer.transform on macOS in
RCTViewComponentView, which routes through RCTUIView's persistence
and anchor point compensation. Remove duplicated anchor point
compensation and hitTest: override that are now handled by RCTUIView.

Update hit testing callers to use the new RCTUIViewHitTestWithEvent
signature with fromView parameter.
