Automatic update from web-platform-testsCorrect serialization of box-shadow and text-shadow
Following https://github.com/w3c/csswg-drafts/issues/2305, the canonical serialization for box-shadow was changed to the color then lengths. https://drafts.csswg.org/css-text-decor-3/#text-shadow-property also defines the canonical serialization for text-shadow as the color and then lengths. This caused the test to fail in Firefox, Chrome, and Safari. Update the test to match the spec in both instances.

Automatic update from web-platform-testsUpdate expected cssText for custom property serialization
See https://github.com/w3c/csswg-drafts/issues/2509#issuecomment-379152590 for the change to target9. Also remove the extra whitespace in target8 and target1 which causes these tests to fail in Chrome and Firefox.
Also remove testcase.propertyName from each test's name as this doesn't exist and just outputs undefined.
