Subject: Migrate Firebase off ObjC module @import statements (#992)

* Migrate Firebase off @import statements

* - Migrate tests and test utils from @import to #import.
  - Update Xcode projects for tests to explicitly link in framework deps.
  - Update check_no_module_imports.sh to look for @imports in tests/test utils/
    integration tests.

* Ensure check_no_module_imports.sh explicitly exits with code 0 on success.
