feat: show download progress when downloading patch artifacts

[bryanoltman]

Description

Updates ArtifactManager.downloadFile to accept an onProgress callback, which is used by the patch command and the android patcher to display download progress.

I hope for this to be helpful in diagnosing #2532

I think we tried this style of on-progress before and found it didn't work as expected (since the stream will get read in one big chunk when reading from disk iirc?), but printing here is still better than nothing and hopefully will help us diagnose.

After testing this on a slow connection, the frequent progress updates cause an unpleasant flickering in the terminal. Going to address that in a followup PR.
