x/tools/gopls: show progress reporting for all commands

[stamblerre]

Right now, it's difficult to tell if a command is executing or to see if it succeeded/failure. We should add progress and error reporting for all commands.

@stamblerre thanks for all of your work on gopls! I would be happy to help out on this issue

Thanks @hasheddan! I actually spent a bit of time looking into this with https://golang.org/cl/247320, but it turned out to be a little more complex than I expected, so it may not be the best issue to start with (basically each command type needs its own progress reporting, which is a little unpleasant). Also, I think this needs to wait until #40527 is resolved.

However, any issue with the help wanted label is totally available. Let me know if any of those sound good to you!

Thanks for following up so quickly @stamblerre! I'll take a look 🙂
