If I understand correctly this adds the property argument to every one of the 647 generated applyValueFoo functions while it can be statically determined in all cases except one. This doesn't seem ideal.

The code generation could be check for 'synonym' concept and only generate the property parameter for it.

I suppose an alternative would be to just generate a separate function for the synonym and do the synonym name mapping when generating the function. This would avoid having to pass the propertyid dynamically and might be generally simpler.

I decided for now it was simplest just to pass the CSSPropertyID as an argument to all the fill layer value applier functions, since their implementations already had a hardcoded propertyID that can now just use the argument.

This seems to have broken two layout tests on iOS:
- imported/w3c/web-platform-tests/css/cssom/cssstyledeclaration-csstext.html
- imported/w3c/web-platform-tests/css/cssom/getComputedStyle-detached-subtree.html

History: https://results.webkit.org/?suite=layout-tests&suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fcss%2Fcssom%2Fcssstyledeclaration-csstext.html&test=imported%2Fw3c%2Fweb-platform-tests%2Fcss%2Fcssom%2FgetComputedStyle-detached-subtree.html

EWS indicated these failures on previous patch in https://ews-build.webkit.org/#/builders/51/builds/20605

Patch was landed manually and might have been different from the one which passed EWS.
