Make generic local values more safe and usable:
- instead of factory, register fiber/coroutine-aware "GLS (general local storage) contexts";
- put up to 4 (normally no more than 2 -- threads and one coroutine implementation) different "tls" variables into one generic, choose correct one from current execution context;
- suitable version of variable will be constructed on demand (no dependency from first usage);
- improve unit test too.

Use generic thread-local value for kernel/groupattrs, crash context and eventlog scope2025-11-27T21:47:44Zkulikovkulikov@yandex-team.com2025-11-27T21:32:45Zurn:sha1:909e306757b2da405daed2e0838e11b65e033c1a
- fix StdThreadLocalImpl -- make static state refcounted, there is no guarantee that static fields will outlive threads or TThreadLocalValues;
- replace thread local values to generic local storage value in some places;
- call runtime Init and replace local values factory;
- don't disable NCurrentThreadEventlog for ytxx runtime, it should now work;
- ensure generic local storage values are allocated after runtime init;
- use function-scope static variables to prevent issues with order of construction and destruction;
- basesearch now almost works with coroutines (with NProfile disabled).
