asan: instrumented LuaJIT memory allocator

This patch adds instrumentation of the internal LuaJIT memory allocator.
It now enables the detection of memory-related errors when using FFI and
within LuaJIT itself. This enhancement improves reliability and debugging
capabilities.

This patch introduces two scenarios for using ASAN with LuaJIT:
- LuaJIT with sysmalloc: use `-DLUAJIT_USE_ASAN=ON`
- LuaJIT with internal memory allocator: use
  `-DLUAJIT_USE_ASAN_HARDENING=ON`

If you want to skip tests when LuaJIT uses the internal memory allocator,
you can check the `LJ_ASAN_HARDENING` environment variable.

The test `test/tarantool-tests/lj-1034-tabov-error-frame.test.lua` has
been disabled under ASAN & LuaJIT's internal allocator due to consistently
failing with a timeout.
