[JS/Common] Fix malformed result of Tensor.fromImage(ImageBitmap) (#16919) ### Description Set `canvas` dimensions to the `ImageBitmap` dimensions, thus fixing a malformed Tensor creation. ### Motivation and Context According to the [HTMLCanvasElement.drawImage() spec](https://html.spec.whatwg.org/multipage/canvas.html#drawing-images): > When the destination rectangle is outside the destination image (the output bitmap), the pixels that land outside the output bitmap are discarded, as if the destination was an infinite canvas whose rendering was clipped to the dimensions of the output bitmap. meaning that `ImageBitmap` pixels exceeding the canvas dimensions will be discarded. Since no canvas dimensions are set for `Tensor.fromImage(ImageBitmap)` if-case, the default 300x150px canvas dimensions are used leading to the creation of malformed Tensors where all the exceeding pixels are discarded and equal to `0, 0, 0, 0` during the subsequent `pixels2DContext.getImageData()` call.
