Summary CSS_STRINGs aren't quoted unless they contain quotes or escape sequences

If you access a CSS_STRING primitive value through the CSSOM, and read the cssText property, the value is unquoted, unless it already contained a quote. This caused problems while I was trying to get the content property of ::before and ::after pseudo-elements using getComputedStyle(). For example, a content property with a value of "X" url(Y) "'Z'" is returned as X url(Y) '\'Z\'', which will cause problems if you try to use this value in other CSS.

I'm also seeing the strings quoted if they contain escape sequences too, though I'm not sure if it applies to all escape sequences.

I am unable to reproduce this bug in attached test cases in Safari 15.6 on macOS 12.5 and results match with all other browsers (Chrome Canary 106 and Firefox Nightly 104). Thanks!
