Export test_options.tags to module-info

The test_options.tags attribute modifies execution behavior when running
tests in ATest Bazel mode. Exporting the value to module-info enables
ATest to add them to the corresponding Bazel target.

Bug: 240928948
Test: manually add `test_options.tags` attribute and run:
    $ refreshmod && \
      cat out/target/product/generic/module-info.json |\
      grep <tags>
