After this, a new target libyqlplugin.so appears. in open-source cmake build.

In case of heavy load and high rps current thread pool implementation seems to have problems at least with contention on lock inside condvar (long futex wait calls from http server listener thread), so try to implement something more efficient:
- replace condvar with TEventCounter implementation without internal lock (pthread condvar maintains waiters wakeup order, thread pool doesn't need it);
- introduce well-known bounded mpmc queue over ring buffer;
- get rid of TDecrementingWrapper;
- add options to turn on new pool in library/cpp/http/server and search/daemons (will remove after adoption);
- make elastic queue ut check both versions;
- workaround problems with android/arm build targets.Revert "YT-19324: move YT provider to ydb/library/yql"2023-06-30T08:13:34Zmax42max42@yandex-team.com2023-06-30T08:13:34Zurn:sha1:3e1899838408bbad47622007aa382bc8a2b01f87

This commit is formed by the following script: https://paste.yandex-team.ru/6f92e4b8-efc5-4d34-948b-15ee2accd7e7/text.
This commit has zero effect on all projects that depend on YQL.
The summary of changes:
- `yql/providers/yt -> ydb/library/yql/providers/yt `- the whole implementation of YT provider is moved into YDB code base for further export as a part of YT YQL plugin shared library;
- `yql/providers/stat/{expr_nodes,uploader} -> ydb/library/yql/providers/stat/{expr_nodes,uploader}` - a small interface without implementation and the description of stat expr nodes;
- `yql/core/extract_predicate/ut -> ydb/library/yql/core/extract_predicate/ut`;
- `yql/core/{ut,ut_common} -> ydb/library/yql/core/{ut,ut_common}`;
- `yql/core` is gone;
- `yql/library/url_preprocessing -> ydb/library/yql/core/url_preprocessing`.
**NB**: all new targets inside `ydb/` are under `IF (NOT CMAKE_EXPORT)` clause which disables them from open-source cmake generation and ya make build. They will be enabled in the subsequent commits.remove kikimr/driver DEPENDS2022-12-02T08:31:25Zqrortqrort@yandex-team.com2022-12-02T08:31:25Zurn:sha1:b1f4ffc9c8abff3ba58dc1ec9a9f92d2f0de6806validate canons without yatest_common2022-11-30T20:47:12Zqrortqrort@yandex-team.com2022-11-30T20:47:12Zurn:sha1:22f8ae0e3f5d68b92aecccdf96c1d841a0334311
