[LL] Add LL API module for JDK 11 tests to support Lincheck tests

- Lincheck is compiled with JDK 11 and the `low-level-api-fir` module is
  based on the JDK 8 toolchain, so we need to add a new module with a
  JDK 11 toolchain to support Lincheck tests. We cannot bump
  `low-level-api-fir` to JDK 11 because `low-level-api-fir-for-ide`
  requires it to be based on a JDK 8 toolchain.
- Using a Gradle test suite is unfortunately not an option, because
  `low-level-api-fir-for-ide` will think that the whole
  `low-level-api-fir` module is compiled with JDK 11 if just a single
  test suite has this toolchain.
