Add 'idl_name' to IdlDefinition, IdlOperation, IdlAttribute etc

IdlDefinition, IdlOperation, IdlAttribute etc should know the name of an IDL file
where they are defined. We want to pass these names to PrivateScriptRunner's methods
so that PrivateScriptRunner can understand the names of JS files of the DOM attributes/methods
that the PrivateScriptRunner is running.

Binding componentization for partial interfaces also need this change.
