Avoid issues when converting large integers to floating point (bug #62212).
* libinterp/corefcn/oct-stream.cc (get_size),
libinterp/corefcn/xpow.cc (xisint),
libinterp/octave-value/ov-base.cc (INT_CONV_METHOD),
libinterp/octave-value/ov.cc (check_colon_operand, range_numel (T, double, T)),
liboctave/numeric/lo-mappers.cc (nint_big, nint),
liboctave/util/oct-inttypes.cc (emulate_mop,
operator - (const double, const octave_uint64)),
liboctave/util/oct-string.cc (rational_approx): Take into account that the
maximum value of (signed or unsigned) integers might change its value if
converted to floating point. In comparisons, check against the first value
*outside* the range of the integer type instead of the last value *inside* its
range.
