Implement stride_view from P1899 (experimental)

[gonidelis]

Although ranges and a part of views have been adopted to C++20 there are certain range adaptors (views) that have not been standardized yet. P1899 proposes stride_view which exposes a strided iterator that iterates through a range with a constant step allowing access over an evenly-spaced subset of it.

Use case example:

auto x = std::vector{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11};

// prints 0 3 6 9
stdr::copy(stdv::stride(x, 3), std::ostream_iterator<int>(std::cout, " "));

Implement stride_view according to p1899.

_{Possible extension of the issue to a collection of C++23 minor proposed facilities.}
