Fix PHAR scoping of trigger_deprecation(), remove stale scoper patchers

- Expose trigger_deprecation() so Symfony's unqualified calls reach it
  (they called a nonexistent function unless the analysed project
  defined it)
- Exclude Composer ClassLoader and InstalledVersions via exclude-classes
  instead of a per-file patcher (also fixes nette/bootstrap)
- Apply the use PhpParser; fix to all files (fixes nette/php-generator)
- Remove patchers that no longer change anything
