Bug 1876262 [wpt PR 44162] - [text-autospace][text-spacing-trim] Update text-spacing shorthand, a=testonly

Automatic update from web-platform-tests
[text-autospace][text-spacing-trim] Update `text-spacing` shorthand

This patch updates the `text-spacing` shorthand parsing:
1. Update the initial value and supported values as per the
   resolution at:
   w3c/csswg-drafts#9511
2. Change the logic to handle `normal` as both properties
   accept `normal` after the spec change above.
3. Fix the canonical order to match the [spec] (`spacing-trim`
   comes first).

Current supported values of longhands are:
* `text-autospace`:    `normal`, `no-autospace`.
* `text-spacing-trim`: `normal`, `trim-start`, `space-all`,
                       `space-first`.

The `text-spacing` shorthands support values above and `none`.

[spec]: https://drafts.csswg.org/css-text-4/#text-spacing-property
