Automatic update from web-platform-tests GetTopExecutionContext method for Canvas rendering contexts BaseRenderingContext2D and CanvasPath access UMA, UseCounters and RuntimeFlags through GetCanvasRenderingContextHost()->GetTopExecutionContext(). This doesn't work and has never worked for PaintRenderingContexts as there is no class that works as a "host" for these contexts. This CL adds a GetTopExecutionContext() function to all canvas rendering 2d contexts that returns a pointer to the execution context directly. For canvas elements and offscreen canvases, this works exactly as before (i.e. host->execution_context). For paint rendering contexts a pointer to the PaintWorkletGlobalScope is passed in on creation. Before this change some new Canvas2D API features would cause crashes in paint worklets.
