YT-21868: Enable stat analysis in some other places

We slightly rework inner workings of stat analysis. For almost any sane use case the behavior is identical, but should compile a little faster.

If you send string literals like `char[N]` or `const char*` make them constexpr. If you can't (e.g. `ex.what()` case) wrap it in `TStringBuf`, if you want the "by the book; 100% right" solution then wrap it in `TRuntimeFormat` instead.

`SetRequestInfo` methods now statically checks the format. Only one error was found -- hooray!

Some other internal stuff was added, a lot removed -- don't worry about it. You won't be able to see the difference
