[Tarantool-patches] [PATCH v2 luajit 0/3] Enable running tests with Valgrind, add CI Valgrind testing workflow

[mandesero--- via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

From: Maksim Tyushev <mandesero@gmail.com>

This patchset enables running LuaJIT tests under Valgrind, with the
option to set custom Valgrind options using the `VALGRIND_OPTIONS`
environment variable. It 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`.
