[fuchsia] Simplify GN for debug symbols CIPD archive

Rather than listing packages with symbols, use deps on the CIPD archive
targets. Break out archives from the main "cipd" group to facilitate
this and add clarity.

This adds gen/fuchsia/engine/web_engine_with_webui/ids.txt to
gen/fuchsia/cipd/all_ids_txt.txt because the webrunner archive depends
on it, but this has no effect since the contents are identical to the
already included gen/fuchsia/engine/web_engine/ids.txt.

Also inline test_packages_for_deps now that it is only used once.

Test: gen/fuchsia/cipd/all_ids_txt.txt contains the same paths as before this CL plus gen/fuchsia/engine/web_engine_with_webui/ids.txt.
