This patch removes the ability to instantiate the LLDB FileSystem class with a FileCollector. It keeps the ability to collect files, but uses the FileCollectorFileSystem to do that transparently. Because the two are intertwined, this patch also removes the finalization logic which copied the files over out of process.
