Auto merge of #24386 - jdm:no-preserve-drawing-buffer, r=nox
webgl: Clear the drawing buffer when preserveDrawingBuffer is false.
This adds an explicit clear operation to a webgl canvas when the preserveDrawingBuffer attribute is false when creating the context. Because we're not using double buffering this may end up making some demos worse (ie. a clear operation at a random time while drawing a frame), but this problem is expected to go away when #24256 is fixed and we move to a multi-buffered frame setup. This change is important at this time because so many babylon.js demos rely on the engine clearing the frame, per the specification.
