Summary [@property] Whitespaces around initial-value should be trimmed

Partially revert https://commits.webkit.org/258215@main. It turns out that WebKit whitespace handling for custom properties (where whitespace is always trimmed) is correct per https://drafts.csswg.org/css-syntax-3/#consume-declaration and this applies to initial-value too. This is test by imported/w3c/web-platform-tests/css/css-syntax/declarations-trim-whitespace.html which we pass and other engines fail. Update the @property tests to the spec.
