Add a way to convert std ranges to wtf containers
https://bugs.webkit.org/show_bug.cgi?id=303699
rdar://165990982
Reviewed by Sam Weinig.
This patch exposes a functor WTF::rangesTo<ContainerT> that will convert
any range to any WTF container that implements a constructor that takes
a std::from_range_t and an std::ranges::input_range.
I added the proper constructors to the wtf Vector and HashMap. The constructors
did not need use the disambiguation tag (std::from_range_t), but I did this
so it would not interfere with any existing constructors.
After this patch the following is possible:
Vector<int> v = std::views::iota(0, 10) | WTF::rangeTo<Vector<int>>;
