[clang-tidy] Check request: readability-use-format

[denzor200]

Needs a check that will find a long concatenation chain and will suggest to use std::format instead.

BEFORE:

std::string message = "Hi " + name + "! You are " + std::to_string(age) +
                      " years old and your height is " +
                      std::to_string(static_cast<int>(std::floor(height))) +
                      "." + std::to_string(static_cast<int>(100 * (height - std::floor(height)))) + " m.";

AFTER:

std::string message = std::format(
        "Hi {}! You are {} years old and your height is {}.{} m.", 
        name, age, static_cast<int>(std::floor(height)),
        static_cast<int>(100 * (height - std::floor(height)))
    );

Should be extension of modernize-use-std-format.
