Issue #5463: Remove _PY_STRUCT_RANGE_CHECKING constant from struct

Browse source 
module, and remove associated code from test_struct.  This was a
mechanism for skipping some of the tests for overflow behaviour when
packing integers; it's no longer necessary.

specified number of bytes. As a special case, ``'0s'`` means a single, empty
string (while ``'0c'`` means 0 characters).
When packing a value ``x`` using one of the integer formats (``'b'``,
``'B'``, ``'h'``, ``'H'``, ``'i'``, ``'I'``, ``'l'``, ``'L'``,
``'q'``, ``'Q'``), if ``x`` is outside the valid range for that format
then :exc:`struct.error` is raised.
.. versionchanged:: 3.1
In 3.0, some of the integer formats wrapped out-of-range values and
raised :exc:`DeprecationWarning` instead of :exc:`struct.error`.
The ``'p'`` format character encodes a "Pascal string", meaning a short
variable-length string stored in a fixed number of bytes. The count is the total
number of bytes stored. The first byte stored is the length of the string, or
