[Test] Add ability to specify directive for test file

Rules of directives resolving:
- If no `MODULE` or `FILE` was declared in test then all directives
  belongs to module
- If `FILE` is declared, then all directives after it will belong to
  file until next `FILE` or `MODULE` directive will be declared
- All directives between `MODULE` and `FILE` directives belongs to module
- All directives before first `MODULE` are global and belongs to each
  declared module
