Introduce support for parameterized classes (#4342)

This commit introduces @ParameterizedClass which builds on
@ContainerTemplate and allows declaring a top-level or @nested test
class as a parameterized container to be invoked multiple times with
different arguments. The same @...Source annotations as for
@ParameterizedTest may be used to provide arguments via constructor or
field injection.

Resolves #878.
