Fully deprecate controller resolver auto mapping

[bobvandevijver]

Symfony 7.1 has deprecated the use of the controller resolver auto mapper functionality in favour of the new mapped route parameters, which have the benefit of being explicit and concise (see symfony/symfony#54455, symfony/symfony#54720 and https://symfony.com/blog/new-in-symfony-7-1-mapped-route-parameters for the discussion and more details).

Note that we already deprecated not setting a value with #1762 to be able to change its default to false with 3.0, but now I propose to fully remove this configuration option with 3.0 instead, with both not setting and true being deprecated. Depending on when 3.0 would be available, removed the option could be postponed to 4.0 if desired.

Ah sorry it took a while to review, but tests need to be adjusted

@ostrolucky No worries. I added the message to the baseline-ignore only, as I believe that the tests shouldn't be changed at this moment. The warning comes from the current configuration default, so it should be automatically solved when changing that in the future.

edit: ah, you're quick, great 👍
