Commit e1870acfac ("Return the correct value when a queue or darray
references an undefined element") added support for specifying the width of
the vector elements stored in a queue or dynamic array, so that an
out-of-bounds access can create a word with the right width.
To get the element width of a queue or dynamic array it uses the
`packed_width()` method. But this method is only implemented for
`netqueue_t` and returns always 1 for dynamic arrays. As a result
out-of-bounds access on a dynamic array will push a vector of the wrong
width onto the stack if the vector element is wider than 1 bit. This will
usually trigger an assert in vvp.
Fix this by moving the `packed_width()` method implementation from
`netqueue_t` to its base class `netdarray_t` so that it works for all types
of dynamic arrays.

The get_signed() method for the netqueue_t class is identical to that of
its base class netdarray_t.
Remove the redundant re-implementation of the method.
