Compares a `basic_const_iterator` with another value.

The `!=` operator is synthesized from `operator==`.

I satisfies /*different-from*/<basic_const_iterator> if std::same_as <I, basic_const_iterator<Iter>> is false.

### Parameters

s | - | a sentinel for `Iter`
y | - | a value to compare with

### Return value

1) base() == s
2) base() < y.base()
3) base() > y.base()
4) base() <= y.base()
5) base() >= y.base()
6) base() <=> y.base()
7) base() < y
8) base() > y
9) base() <= y
10) base() >= y
11) base() <=> y

### Notes

Overload (1) can be used to compare two `basic_const_iterator<Iter>` values if `Iter` models sentinel_for<Iter>.
