ranges and views for stack, queue, and priority_queue

I've always felt that exposing iterators for `std::stack` or `std::queue` doesn't quite make sense because iterating over them would typically change their state.

That said, the range features introduced in C++20/23 are just too tempting. 😄

I bet many C++ developers have had this thought at least once:

queue | views::values | views::to<std::vector>()

...or more generally, "What if I could use the ranges pipeline directly on a queue or stack?"

So I spent some time experimenting to see if I could make it work. Here's what I came up with.
