Improve TGenericLocalValue, allow mixed thread-fiber-etc values2026-06-08T18:16:24Zkulikovkulikov@yandex-team.com2026-06-08T17:33:12Zurn:sha1:a6848417fed706ec4f89a589c2ea9aa54eb39829
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.

YT-22593: Reduce TString usage in core/misc2026-06-06T22:31:50Zbabenkobabenko@yandex-team.com2026-06-06T22:15:06Zurn:sha1:ffc038d5a916cec181915795ca4b45f07ee2ae05

Cache process/thread id getters and use them in TError origin capture2026-06-06T21:16:49Zbabenkobabenko@yandex-team.com2026-06-06T20:52:00Zurn:sha1:f10c7206fb31af8057446bceef9707aabaa9456e
## Motivation
Profiling the YT master Automaton thread showed TOriginAttributes::Capture (run on every non-OK TError) spending ~60% of its time in a getpid() syscall — uncached on glibc >= 2.25. NYT::GetCurrentThreadId() (gettid) feeds hot thread-affinity / log-manager checks on the same thread.
## Changes
- New library/cpp/yt/system/process_id.* with cached GetProcessId(); GetSystemThreadId() now caches the kernel tid in TLS. Both caches reset in the child after fork.
- Moved thread_name.{h,cpp} from misc to system.
- Removed GetCurrentProcessId/GetCurrentThreadId shims from yt/yt/core/misc/proc.{h,cpp}; migrated all callers to NYT::GetProcessId / NYT::GetSystemThreadId.
- TOriginAttributes::Capture uses the cached getters; recorded Tid is now the real kernel tid (matches perf/ps).
- Added microbenchmarks (library/cpp/yt/system/benchmarks, yt/yt/core/benchmarks/error.cpp).
## Microbenchmarks (release)
| | before | after |
|---|---|---|
| getpid | 101 ns | 0.33 ns |
| gettid | 102 ns | 1.64 ns |
| Capture | 161 ns | 50 ns |
| failed TError | 221 ns | 74 ns |
