[Framework bundle] Cleanup error and exception handlers on Kernel shutdown #53812
Description
Symfony version(s) affected
7.0.0
Description
PHPUnit 11 checks for any leftovers in error handlers sebastianbergmann/phpunit#5619
How to reproduce
Run FrameworkBundle->boot() in phpunit test.
It results in Test code or tested code did not remove its own exception handlers thrown by phpunit.
Possible Solution
Introduce FrameworkBundle::shutdown() that would cleanup error handler set in boot(). IMO it's reasonable to have some cleanup in shutdown() of things initiated in boot().
