Reviewed by Darin Adler.

To make replacing makeprop.pl easier in https://bugs.webkit.org/show_bug.cgi?id=247470
this updates the generated output to consistently use the following stylist choices:

- Always use fully scoped name for CSSPropertyIDs (this will also make it a bit
easier to move to a scoped enum at some point).
- Use the parameter name "id" for CSSPropertyID parameters in generated functions.
- Move all the fullly static function bodies generated for CSSPropertyNames.gperf to
be consecutive.
- Add a missing space in the static part of isInheritedPropertyTable so that all
the true's look the same.
