As discussed in #49585, we try to extract messages from all src/ directory in `translation:debug` and `translation:extract` commands. But, it's not necessary to look into all files, as we can easily detect if a file contains something about translation (with some regexes).

This PR filter files before messages extraction, and it divide by at least 3 the time used to extract messages from an app with 100 000 php files.
