feat(php): mark source and test roots from composer.json autoload (#1602)

Folders in composer.json's autoload.psr-4 become Sources Roots and those in autoload-dev.psr-4 Test Sources Roots (string or array values; paths into vendor/ or outside the folder are skipped). It runs before the package.json case, so a Laravel app's tests/ is credited to composer.json, and editing composer.json reruns detection.
