Add recursion depth to app directory retrieval

This commit introduces a 'RecursiveDepth' attribute as an enhancement to the app directory retrieval in the Wox plugin system. This allows more flexibility in controlling the depth of recursion when retrieving apps. Additionally, this commit alters the 'GetAppDirectories' implementation on both macOS and Windows to reflect this new feature.
