[Tarantool-patches] [PATCH v3 luajit 0/2] Enable running tests with Valgrind, add CI Valgrind testing workflow

[mandesero at gmail.com]

From: Maksim Tyushev <mandesero at gmail.com>

This patchset enables running LuaJIT tests under Valgrind, with the
option to set custom Valgrind options using the `VALGRIND_OPTIONS`
environment variable. Please note that this environment variable must
be set before building, and any updates to it will require a project
rebuild. The patchset also introduces a Valgrind testing workflow
with three scenarios: full checks, and two memory checks without leak
detection, where memory is filled with `0x00` and `0xff`.

Some tests consistently fail under Valgrind due to various reasons,
such as SIGPROF, timeouts, or flaky behavior. These tests are
disabled when `LUAJIT_USE_VALGRIND=ON`.

Branch: https://githb.com/tarantool/luajit/tree/mandesero/lj-3705-turn-off-strcmp-opt-in-debug
Issue: https://github.com/tarantool/tarantool/issues/3705

Changes in v3:
 - Squashed commits 'run tests with Valgrind (1/3 v2)' and
   'disable failed tests (3/3 v2)'.
 - Simplified `.github/actions/setup-valgrind`, now dependents
   on `.github/actions/setup-linux`.
 - Updated `test/CMakeLists.txt` with minor adjustments.
