Add JSCCustom and V8Custom as extended IDL attributes

This will help avoid having to add #ifdefs to the IDL files to support the V8 bindings.

In this patch, I define JSCCustom and make use of it in a few IDL files.  I also modify Document.idl to make use of V8Custom, which is known only to the CodeGeneratorV8.pm module (that has yet to be upstreamed).

I did not add JSCCustomGetter or JSCCustomSetter since they are not needed.  I could add those for completeness, but it seemed better to just focus on what is actually needed.

This will do the wrong thing if someone includes both "Custom" and "JSCustom" for the same attribute; and it won't report an error. It would be better to use || instead or consider it an error.
