IDL: Support [TypeChecking=Interface] correctly on indexed setters

Normally, [TypeChecking=Interface] can be set either on an interface as
a whole, affecting all its definitions (attributes and methods), or on
individual definitions. But for indexed setter definitions

  setter ElementType (unsigned long index, ElementType value);

it had to be set explicitly for the setter definition; setting it only on
the interface as a whole did not work.

This change affects the following interfaces with indexed setters:

  SVGLengthList
  SVGNumberList
  SVGPathSegList
  SVGPointList
  SVGTransformList
