common: fs: Use the normal directory iterator in *Recursively functions 

MSVC's implementation of recursive_directory_iterator throws an exception on an error despite a std::error_code being passed into its constructor. This is most likely a bug in MSVC's implementation since directory_iterator does not throw an exception on an error.

We can replace the usage of recursive_directory_iterator for now until MSVC fixes their implementation of it.
