[MotionMark] De-virtualize some `CanvasRenderingContext` methods
https://bugs.webkit.org/show_bug.cgi?id=281462
rdar://137913852
Reviewed by Simon Fraser.
De-virtualize these methods which show up a non-trivial amount in the traces:
- CanvasRenderingContext::delegatesDisplay()
- CanvasRenderingContext2DBase::effectiveDrawingContext()
- CanvasRenderingContext2DBase::drawingContext()
This offers a ~2% improvement on the Canvas Lines test suite.
