This change makes it so that the Platform classes can now handle installing GStreamer dependencies and properly setting up the environment including when cross-compiling. For Windows and Linux is now installed into `target/dependencies/gstreamer` when not installed system-wide. In addition: 1. Creating and moving existing environment path append helpers to `util.py`. 2. Combining the `set_run_env` and `build_dev` functions and moving some outside code into them so that it can be shared. Now code that used to call `set_run_env` calls `build_dev` and then `os.environ.update(...)`. 3. Adding Python typing information in many places. Signed-off-by: Martin Robinson <mrobinson@igalia.com>
