cmake: integrate Lua API tests

Build Tarantool:

```
CFLAGS="-fsanitize=fuzzer-no-link" LDFLAGS="-fsanitize=fuzzer-no-link" CC=clang CXX=clang++ cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug -DENABLE_FUZZER=ON -DLUAJIT_NUMMODE=2
```

Build luzer:

```
git clone https://github.com/ligurio/luzer
CC=clang-21 CXX=clang++-21 cmake -S . -B build
cmake --build build/ --parallel
```

Run test:

```
LUA_CPATH='./luzer/build/luzer/?.so;;' LUA_PATH='./luzer/?/init.lua;;' ./src/tarantool ./test/fuzz/lua-tests/src/tests/lapi/bitop_bxor_test.lua
LSAN_OPTIONS=suppressions=$(pwd)/asan/lsan.supp ASAN_OPTIONS=heap_profile=0:unmap_shadow_on_exit=1:print_suppressions=0 tarantool tarantool_csv.lua
```

Follows up commit 8ad443d
("cmake: introduce a module to build fuzzing tests").

TODO:
- integrate with LSAN_OPTIONS and ASAN_OPTIONS
