Why did you remove the switch check kDisableTorClientUpdaterExtension? Current master still has that switch.
The latest commit only added AsTestingProfile check

Other conditions are moved to BraveTorClientUpdater::Register(). - 81bae87#diff-5293ed891460b117107c7923e61926efR127
The intension of this refactoring is moving tor update specific logic to BraveTorClientUpdater::Register() like BraveTorClientUpdater::Cleanup(). WDYT?

@simonhong can you also double-check that deps are removed/added for this file and the file it was added to?
