Add regression tests for nested dynamic arrays and queues

SystemVerilog allows to declare signals of nested unpacked types. E.g. a
queue of dynamic arrays.

This is currently not supported by Icarus. Add regression test nevertheless
to check that this is reported as a non-supported construct and does not
result in random crashes.
