gitmodules: exclude unnecessary submodule cloning for esp32 (project-chip#42007)

- ESP32 has its own clones for mbedtls, FreeRTOS-Kernel, lwip and it
  uses it sources it from esp-idf sdk. So don't clone it into
  third_party directory.
- ESP32 platform does not require boringssl either.
- Also, libtrustymatter is specific to NXP platform, so tagged it with
  platform nxp.
