[csswg-drafts] Pull Request: [css-syntax-3] Remove duplicate token stream creations

cdoublev has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

== [css-syntax-3] Remove duplicate token stream creations ==
[tokenize](https://drafts.csswg.org/css-syntax-3/#css-tokenize) maps a stream of code points into a stream of tokens:

  > To tokenize a stream of code points **into a stream of CSS tokens** `input`, repeatedly consume a token from `input` until an `<EOF-token>` is reached, pushing each of the returned tokens into a stream.

But a stream of tokens is also created with its result:

  - in [normalize into a token stream](https://drafts.csswg.org/css-syntax-3/#normalize-into-a-token-stream):

  > 3. [...], [tokenize](https://drafts.csswg.org/css-syntax-3/#css-tokenize) the result, then create a new token stream with those tokens as its tokens, and return it.

  - in [consume the value of a unicode-range descriptor](https://drafts.csswg.org/css-syntax-3/#consume-the-value-of-a-unicode-range-descriptor):

  > 1. Let `tokens` be the result of [tokenizing](https://drafts.csswg.org/css-syntax-3/#css-tokenize) [...]. Let `input` be a new token stream from `tokens`.
