slice_length: avoid implementation-defined division by negative number

3dc52575f0 slice_length: avoid implementation-defined division by negative number 
In CircuitPython (only), a the slice assignment to [-1👎-3] of an
ndarray of length 1 caused a crash.  This appears to be because in
CircuitPython, the internal pointer of an empty array was NULL rather than
pointing at some memory which happened to be valid and assignable.

This appears to be a corner case of how integer promotion rules work in C.
The expression `slice.stop - slice.start + (slice.step + correction)`
is type `unsigned long` and on a LP64 platform its value is
18446744073709551614.  This led to the function returning that this slice
had length 1 instead, during the automated tests.

By casting to signed types capable of holding indices and sizes, the
problem is corrected on both platforms.

Deleting "#define MODULE_ULAB_ENABLED (1)" 
Since the micropython.mk file has added the following line

```
CFLAGS_EXTRA = -DMODULE_ULAB_ENABLED=1
```

There's no need to add #define MODULE_ULAB_ENABLED (1) in the mpconfigport.h.Or it would make redefined errors while compiling code.

903016ec44 slicing: add test of slice assignment 
This tests that ulab and python3/numpy match on various slice assignments
that preserve the length of the array.  slice assignments that change
the length of the array are not tested.

Unlike the case of "load slice", this case of "modify slice" is not
compared to the built in list type, since "modify slice" is only
implemented in micropython for simple (stride=1) slices.

f9fabc5079 Fix handling of negative indices 
I don't know why, but mp_seq_get_fast_slice_indexes adjusts "stop" in a
surprising way, and that led to the (remaining) differences in slicing
between ulab and built-in lists.

    // If the index is negative then stop points to the last item, not after it
    if (indexes->step < 0) {
        indexes->stop++;
    }

Call the underlying routine, mp_obj_slice_indices, instead.
