LibWeb: Add CSS.escape() JS function

Browse source 
This is the `CSS` namespace defined in IDL here:
https://www.w3.org/TR/cssom-1/#namespacedef-css , not to be confused
with our `Web::CSS` namespace. Words are hard.

`CSS.escape()` lets you escape identifiers that can then be used to
create a CSS string.

I've also stubbed out the `CSS.supports()` function.
