[TASK] sysext/install/Check: check PHP extension "tokenizer"

Various libraries incorporated by TYPO3 use the "token_get_all"
function, crashing PHP execution if the "tokenizer" extension is not
loaded.

The system environment pre-check now checks the presence of the PHP
extension. Also, Composer now requires the presence of the
`ext-tokenizer` module.
