[FEATURE] Introduce native support for Symfony Console

This feature allows to add Commands based on Symfony
Console, and also introduces a new binary located in
typo3/sysext/core/bin/t3console.

This effectively removes the need for typo3/cli_dispatch.phpsh
which is not part of any system extension.

Resolves: #73042
Releases: master
