Reviewed by Tim Nguyen.

Revert the change from https://commits.webkit.org/260157@main that made background-color
serialize first. This is being discussed in https://github.com/w3c/csswg-drafts/issues/8496,
but while it's discussed, it seems good to change the behavior back since that matches
other browsers and some WPT test expectations.

* LayoutTests/editing/deleting/paste-with-transparent-background-color-expected.txt:
Change expectations back to expect background-color to be serialized last, after the other
longhands that are part of the background shorthand
* LayoutTests/editing/deleting/paste-with-transparent-background-color-live-range-expected.txt: Ditto.
* LayoutTests/fast/backgrounds/background-shorthand-after-set-backgroundSize-expected.txt: Ditto.
* LayoutTests/fast/backgrounds/background-shorthand-after-set-backgroundSize.html: Ditto.
* LayoutTests/fast/backgrounds/background-shorthand-with-backgroundSize-style-expected.txt: Ditto.
* LayoutTests/fast/backgrounds/background-shorthand-with-backgroundSize-style.html: Ditto.
* LayoutTests/fast/css/remove-shorthand-expected.txt: Ditto.
* LayoutTests/fast/dom/background-shorthand-csstext-expected.txt: Ditto.
* LayoutTests/fast/dom/background-shorthand-csstext.html: Ditto.

* Source/WebCore/css/CSSProperties.json: Move background-color to the end of the list of longhands
for the background shorthand.
