Support class members for test parameters resolution (enhancement)

[olegnekludov]

In ceylon.test "1.3.0" if I use class attribute as parameters source there is exception (if I use value outside class - its ok): ceylon.language.meta.model.TypeApplicationException "Cannot apply a member declaration with no container type: use memberApply":

class NestedArrayTest() {
    shared {[ClassDeclaration, [String, String]]*} testJsonValuesParams => {
        [`class DummyArraySequential`, ["[", "]"]]
    };

    test
    parameters(`value testJsonValuesParams`)
    shared void testJsonValues(ClassDeclaration clsDecl, [String, String] brackets) {
...

Similarly, I find it very useful to compose test cases into bigger test cases, and to collect them in a toplevel object for this purpose:

alias Test => [String, Value];
object tests {
    shared Test test1 = ["foo", Str("foo")];
    shared Test test2 = ["bar", Str("bar")];
    shared Test test3 = [test1[0] + "," + test2[0], Comp(test1[1], test2[1])];
    
    shared Test[] allTests = [test1, test2, test3];
}

test
parameters (`value tests.allTests`)
shared void myTest(String text, Value expected)
        => assertEquals { expected = expected; actual = parse(text); };

But using tests.allTests for the parameters is currently not supported either. Fortunately, there’s a simple workaround:

shared Test[] allTests => tests.allTests;

parameters (`value allTests`)
