/// @assertion An external variable declaration D is treated as an external
/// getter declaration and possibly an external setter declaration. The setter is
/// included if and only if D is non-final. The return type of the getter and the
/// parameter type of the setter, if present, is the type of D (which may be
/// declared explicitly, obtained by override inference, or defaulted to dynamic).
/// The parameter of the setter, if present, has the modifier covariant if and
/// only if D has the modifier covariant (the grammar only allows this modifier
/// on external instance variables).
///
/// @description Checks that declaration
///  class A {
///    external static var i1;
/// desugared as
///  class A {
///    external static dynamic get i1;
///    external static void set i1(dynamic _);
