[clang-tidy][readability-container-contains] Extend to any class with contains (#107521)
This check will now work out of the box with other containers that have a
`contains` method, such as `folly::F14` or Abseil containers.

It will also work with strings, which are basically just weird containers.
`std::string` and `std::string_view` will have a `contains` method starting with
C++23. `llvm::StringRef` and `folly::StringPiece` are examples of existing 
implementations with a `contains` method.
