LibWeb: Factor out a function to generate IDL enumerations

Browse source 
The prototype header generation was getting a bit long.

This is also a step towards generating code for IDL files only
containing an enum definition without any interface. In that case we
can't put the enum definitions alongside the prototype - there is no
prototype to speak of.
