Move uses of to_bytes, to_text, to_native to use the module_utils version (#17423)

We couldn't copy to_unicode, to_bytes, to_str into module_utils because
of licensing.  So once created it we had two sets of functions that did
the same things but had different implementations.  To remedy that, this
change removes the ansible.utils.unicode versions of those functions.

 well for modules as well or if we should give the module_utils API explicit
 switches so that modules can choose to operate with text type all of the time.
 
+Helpers
+~~~~~~~
+
+For converting between bytes, text, and native strings we have three helper
+functions.  These are :func:`ansible.module_utils._text.to_bytes`,
+:func:`ansible.module_utils._text.to_native`, and
+:func:`ansible.module_utils._text.to_text`.  These are similar to using
+``bytes.decode()`` and ``unicode.encode()`` with a few differences.
+
+* By default they try very hard not to traceback.
+* The default encoding is "utf-8"
+* There are two error strategies that don't correspond one-to-one with
+  a python codec error handler.  These are ``surrogate_or_strict`` and
+  ``surrogate_or_replace``.  ``surrogate_or_strict`` will use the ``surrogateescape``
+  error handler if available (mostly on python3) or strict if not.  It is most
+  appropriate to use when dealing with something that needs to round trip its
+  value like file paths database keys, etc.  Without ``surrogateescape`` the best
+  thing these values can do is generate a traceback that our code can catch
+  and decide how to show an error message.  ``surrogate_or_replace`` is for
+  when a value is going to be displayed to the user.  If the
+  ``surrogateescape`` error handler is not present, it will replace
+  undecodable byte sequences with a replacement character.

-
-        The initial :func:`to_unicode` call will ensure text is
-        a :class:`unicode` string.  Then, :func:`to_bytes` will turn that into
-        a byte :class:`str` with the specified encoding.
-
-    Usually, this should be used on a :class:`unicode` string but it can take
-    either a byte :class:`str` or a :class:`unicode` string intelligently.
-    Nonstring objects are handled in different ways depending on the setting
-    of the :attr:`nonstring` parameter.
-
-    The default values of this function are set so as to always return a byte
-    :class:`str` and never raise an error when converting from unicode to
-    bytes.  However, when you do not pass an encoding that can validly encode
-    the object (or a non-string object), you may end up with output that you
-    don't expect.  Be sure you understand the requirements of your data, not
-    just ignore errors by passing it through this function.
