FileAPI: Implement FileSystemQuotaUtil on SandboxFileSystemBackendDelegate

This makes SandboxFileSystemBackendDelegate to implement FileSystemQuotaUtil
instead of Sandbox/SyncFileSystemBackend so that it can remove a thin layer from
those backends.

And also moves common implementations of FileSystemBackend
(e.g. CreateFileStreamReader()) into the delegate.
