generalize css vendor prefix for es53

This CL deletes the vendor-prefix css properties in the css whitelist.
To do that without breaking es53 users, this adds some vendor prefix
hxandling to the es53 css sanitizer.

This isn't quite feature parity with the es5 css sanitizer, because
es53 won't handle @-webkit-keyframes and other such cases, but that
isn't a new problem, and es53 is going away.

This is somewhat duplicative of a similar function in CssPropertyPatterns.
