Add WPT test validating that drawImage writes to the layer

Added a WPT to check that using `drawImage` inside a layer writes the
image to the layer and not it's parent directly. The test uses
`drawImage` with another canvas as source, inside a layer that applies a
filter and uses the global composite operation `xor`. In its reference,
the same drawing commands are used in the main canvas inside the layer,
to verify that the filter effect is applied on the image, and that the
compositing of the `drawImage` operation is done with the layer's content
and not the parent's.
