Add --quiet flag to run-tests.php

The large amount of output is annoying when working locally. Especially when running a single test repeatedly, the terminal buffer quickly gets filled.

Targetting 8.2 because conditionally passing the flag in scripts is annoying.

I have no issue with this PR, but see https://askubuntu.com/questions/25077/how-to-really-clear-the-terminal.

What I often do in my workflow:

• Make a change to php-src
• Run all tests
• Fix a test by tweaking the source and re-running it
• Go to the next test

By the time I'm ready to move on to the next test, my buffer has been completely filled with useless information about my machine, which yes, is indeed the same one it was 2 seconds ago. 😛 It's not a huge issue, but it's annoyed me since 2020. 😄

Oh, I also just discovered the -l flag in run-tests.php I was unaware of. That's going to help a lot!

If -l solves the issue for you fine, but I guess the --quiet option still can make sense for such workflows.

I agree, I would like less output regardless. I'd still like to improve this by making the summary less noisy when running singular tests.
