Check that the signedness of class properties is handled correctly

* When passing as a value to a system function
Check this for both when accessing the property from within a class method
as well as accessing it on a class object.

Check that the signedness of the return value of methods is handled

Check that the behavior of the Verilog AMS `abs()` function is correct when
its argument is a function call. Check this for both vector as well as real
types.
This test is largely a copy of the existing vams_abs2 test, just replacing
the identifier argument with a function call argument.

Check that static class properties can be accessed for read and write and
that they are shared between all instances of a class type.
Check that this works for the following 3 cases
* accessing the static property in a class function or task
* accessing the static property in a class function or task using `this`
* accessing the static property on a class object instance

Check that it is not possible to declare a variable in a package without an

Check that it is possible to declare the type separately from the direction
for non-ANSI integer, time and atom2 ports. Check that it is possible to
both declare the type before and after the direction.
For integer, time and atom2 types the range specification on the port
direction declaration should be empty, rather than the implicit packed
dimension of the integer type.

Check that the compatibility of signals of enum data type across module

Check that it is possible to define the data type of a non-ANSI module port
in a separate declaration from the port direction. Add tests for both the
type declared before the port direction and for the type declared after the

Note that this doesn't work yet correctly for integer type module ports
yet, so there are no tests for this. This will be addressed in follow up
work.

Currently only dynamic arrays and queues of atom2 and vector types are
supported. Add support for packed arrays. Since these three types are
essentially handled the same internally supporting this only requires to
allow to elaborate a packed array base type.
Factor out type elaboration into a helper function that can be shared
between the elaboration of the base type of a dynamic array or queue and
the type for other signals. This gives consistent behavior and will also
make it easier to support additional base types for dynamic arrays or
queues.
Note that it is not yet possible to index elements of packed array dynamic
arrays or queues. But neither is it possible to do a bit select for vector
or atom2 type dynamic arrays or queues yet. Supporting this needs some
additional work.
There is one test that declares a queue of a struct type, but doesn't use
it since it is not supported. With this change a error will generated when
trying to declare a queue of a struct. So update that test to not declare
the variable so it does not fail.
