Fix EZP-24612: Switch CS to PSR-2

[lolautruche]

Used PHP-CS-Fixer with symfony level, but deactivating the following fixers:

• concat_without_spaces (actually enforces concat_with_spaces from contrib level)
• empty_return
• phpdoc_params
• spaces_cast

Go home ezrobot, you're obsolete :-D
Either that, or some configs have to be changed...

[lolautruche]

@gggeek Actually, that was helpful 😉 . It showed wherever things need to be fixed manually.

OK, let's try another round

Used PHP-CS-Fixer with only psr2 level.

Why use it if phpcbf fixes much more issues?

[andrerom]

that could be an alternative, but the remaining issues here is in our opinion to strict, it is forcing multiline conditions to be placed on one line, often breaking the soft limit line length, and sometimes also the hard one potentially.

Note that @ezrobot is pretty long (no cache yet for php-cs-fixer on Jenkins)

[pspanja]

+1 with last bits fixed.

[lolautruche]

Everything has passed now. Merging

Goodbye ezcs, you were the pinnacle of readability... 😭
