LibWeb: Resolve and paint simple SVG masks

Browse source 
This allows applying SVG <mask>s to elements. It is only implemented for
the simplest (and default) case:

	- mask-type = luminance
 	- maskContentUnits = maskContentUnits
 	- maskUnits = objectBoundingBox
	- Default masking area

It should be possible to extend to cover more cases. Though the layout
for maskContentUnits = objectBoundingBox will be tricky to figure out.
