LibWeb/CSS: Serialize Supports::Declaration as original representation

Browse Source 
Fixes some WPT tests that expected `supports(foo:bar)` to serialize as
`supports(foo:bar)`, instead of `supports(foo: bar)` with a space
between.

Reading the original_full_text directly also lets us delete
Declaration::to_string(), which was only used here.
