This removes direct file access from within flutter_tools in favor of using `package:file` via a `FileSystem` that's accessed via the `ApplicationContext`. This lays the groundwork for us to be able to easily swap out the underlying file system when running Flutter tools, which will be used to provide a record/replay file system, analogous to what we have for process invocations.
