MacDue 5df4e64eb7 LibWeb: Implement SVG preserveAspectRatio attribute
This attribute is used to define how the viewBox should be scaled.
Previously the behaviour implemented was that of "xMidYMid meet", now
all of them work (expect none :P).

With this the Discord login backend is now correctly scaled/positioned.

This also brings our SVG code a little closer to the spec! With spec
comments and all :^)

(Minor non-visible update to layout tests)
