testing: implement -timeout flag

[eliasnaur]

Note that this PR renames the existing -timeout flag to -vol-timeout.

Should reduce the multi-hour hangs on macOS builders (#4995) to ~10 minutes.

Is that a problem for anyone?

Yes please! 😸

Just wondering do we actually need to rename the flag? Do your other changes actually require that, @eliasnaur?

I'm not sure I understand your question. Are you suggesting to keep -timeout for volume timeouts, or to overload its meaning to depend on whether you're running tinygo flash or tinygo test?

I think that is what I meant.

It's possible, but I don't think it's worth the confusion. Besides, "timeout" is not a great name for something as specific as "the length of time to retry locating the MSD volume to be used for flashing".

Fair point. In that case, how about renaming it to flash-timeout?

The timeout is for waiting for the flash volume, not flashing in itself. For example, if you're flashing through a debugger -flash-timeout would be ignored.

How about -volume-timeout?

[deadprogram]

Sounds good to me!

@eliasnaur can you please rebase this branch against the latest dev? Not sure why the CI is failing.

[eliasnaur]

I already did, and I'm not sure either.

For some reason, my Linux VM fails to run make tinygo-test with the following error:
