Capture stderr to temp file and output it in test results

• new feature
• BC break: no (only additional output in test results)

Any idea why output tests on my computer works just fine but fails in GitHub actions? Output does not match but it seems it should. I suspect some whitespace difference but cannot find it.

I still struggle to find what causes tests to fail only in CI. I identified that it is caused by spaces only lines in actual output on CI that does not happens on by local build. But I have no idea why. I will do some more experimentation to find it.

Finall I made it pass. I also fixed one coding standard error.

@dg @milo Could oyu check it out and let me know what do you think?

Looks great. I'll polish it a little bit and I'll merge it.

@MartinMystikJonas Are you OK with such modifications? https://github.com/milo/tester/tree/MartinMystikJonas-stderr-file

[MartinMystikJonas]

@milo Looks OK

[MartinMystikJonas]

@milo Is there anything I should do now to finish this PR?

[milo]

Thank you. I've merged it.

Do you have any idea why the RunnerOutput\OutputHandlers.phpt test is not passing on Windows? Difference is in progress line in OutputHandlers.expect.console.txt:

actual:

PHP 8.2.0beta3 (cgi-fcgi) | …

FFFF...ssss

expected:

PHP 8.2.0beta3 (cgi-fcgi) | …

I have seen something similar when temp dir was not purged between individual tests so order of executed tests prioritized failed ones. Why it happens on windows I do not know.

Bingo, thanks!
