RFR: 8338678: Erroneous parameterized type represented as <any>

[Jan Lahoda]

Consider code like:

class C {
    Undefined u1;
    Undefined<UndefinedParam> u2;
}


The types of both `u1` and `u2` are erroneous, but the internal properties of the types are different. For `u1`, the erroneous type keeps the name (`Undefined`), while for `u2`, the type is simply `<any>`.

The proposal here is to improve the error recovery, and create a parameterized error type for the second case.
