Added more sanitizer tests

Pull request overview

This PR expands the sanitizer test surface by adding protobuf-free Lua acceptance tests (run via ctest) and by improving the Lua runtime bindings/concurrency so those tests can safely drive in-process module code paths (NRPE/NSCA/Scheduler/etc.) under ASan/UBSan/LSan. It also makes the web backend build behavior more robust by conditionally building nscp_mongoose and providing clearer CMake diagnostics when dependencies are missing.

Changes:

• Add NSCP_ADD_LUA_TEST() and register multiple lua_*_test ctests guarded by relevant module build flags.
• Introduce Lua-side acceptance tests plus an updated Lua test harness (test_helper.lua) compatible with Lua 5.4 / current NSClient++ Lua API.
• Add Lua core bindings (query_target, query_forward) and a process-wide Lua “GIL” to avoid cross-thread lua_State corruption, while releasing it around blocking/re-entrant core calls.
