LibWeb: Clarify naming of TokenStreams in parse_css_value()

Originally, the input was named `tokens`, and we later created a
`tokens_without_whitespace` from the filtered contents of `tokens`.
Since `tokens_without_whitespace` is what we actually want to use while
parsing, let's rename `tokens` -> `unprocessed_tokens` and use the
`tokens` name for the processed ones.
