Add "--browse" to "arc upload" and update behavior, particularly "--json"

Summary:
Ref T13528. Provide a "--browse" flag to open files after they are uploaded.

Update the code to use modern query strategies.

This impacts the output of "--json", which was just raw "file.info" output before and could not represent the same path being passed several times (arc upload X X).

Test Plan: Ran arc upload with --browse and --json.
