Added a not implemented error on platforms without long ints

[DavePutz]

Issue #2812 - throw a NotImplementedError instead of "AttributeError: 'module' object has no attribute" for time functions that require long ints on platforms that do not support those.
It will now look like:

>>> import time
>>> dir(time)
['__class__', '__name__', 'localtime', 'mktime', 'monotonic', 'monotonic_ns', 'sleep', 'struct_time', 'time']
>>> time.time()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NotImplementedError: No long integer support

Sorry, I should have been clearer in #2812, I was thinking more like this:

STATIC mp_obj_t time_not_implemented(void) {
    mp_raise_NotImplementedError(translate("No long integer support"));
}
MP_DEFINE_CONST_FUN_OBJ_0(time_not_implemented_obj, time_not_implemented);

and then reference that in `time_modules_global_table, for each unimplemented function, e.g., for one of them:

    { MP_ROM_QSTR(MP_QSTR_time), MP_ROM_PTR(&time_not_implemented_obj) },

Locally, I tried using #if inside each function to select either the longint impl or an mp_raise_NotImplementedError(), but that seems to generate more code.

By the way, I would suggest that you not work on the master branch in your fork. Instead, create a branch for this particular fix, and commit to that branch. Then your master won't get out of sync with upstream. See https://learn.adafruit.com/contribute-to-circuitpython-with-git-and-github/always-work-on-a-branch.

Also, you will need to do make translate before pushing your changes, because you've added a new translate() string. Otherwise the builds will fail.
