LibWeb: Use CSS::Size for computed size and max-size values

Browse source 
This patch changes the *computed* representation of the following CSS
properties to use CSS::Size:

- width, min-width, max-width
- height, min-height, max-height

A few things had to change in order for things to keep working,
but I tried to keep the diff to a minimum.

The main trouble was that `min-width` and `max-width` can't actually be
`auto`, but they *can* be `none`. We previously treated `auto` as a
valid value (and it behaved mostly like `none`).
