SI-8582 emit InnerClasses attribute in GenBCode

I removed the `-bcode` test since we have a build that passes
`-Ybackend:GenBCode` to all tests.

Short intro do the [`InnerClass` attribute][1]:

  - A class needs one `InnerClass` attribute for each of its nested
    classes

  - A class needs the `InnerClass` attribute for all (nested) classes
    that are mentioned in its constant pool

The attribute for a nested class `A$B$C` consists of the long name of
the outer class `A$B`, the short name of the inner class `C`, and
an access flag set describig the visibility.

The attribute seems to be used for reflection.

+Mirror classes have the same InnerClass attributes as the corresponding module class:

+
+An outer class has a InnerClass attribute for direct nested classes
+ className[A1$B1] outerClassName[A1] innerName[B1] access[1]
+A nested class has an InnerClass attribute for itself (and also for its nested classes)
+ className[A1$B1] outerClassName[A1] innerName[B1] access[1]
+ className[A1$B1$C1] outerClassName[A1$B1] innerName[C1] access[1]
+C1 is a nested class, so it has an InnerClass attribute for itself.
+Because that attribute leads to an entry for B1 in the constant pool, C1 needs an InnerClass attribute for B1.
+ className[A1$B1] outerClassName[A1] innerName[B1] access[1]
