LibWeb: Create EdgeStyleValue for BackgroundPositionXY with no offset

Browse source 
When specifying either `background-position-x: right` or
`background-position-y: bottom` without an offset value no
EdgeStyleValue was created.

However, the spec says the offset should be optional.

Now, if you do not provide an offset, it creates the EdgeStyleValue
with a default offset of 0 pixels.
