Adds methods to get and set the window size, as well as to query the
window's scale factor. This is useful both for custom clients, and for
building a window resize plugin to prototype what will eventually likely
be a system channel.

Plugins may need to be able to access functions affecting the GLFW
window (e.g., a plugin to resize the window). This restructures the API
to create a distinction at both the C and C++ level between the window
controller, which provides access to high-level behaviors driving the
Flutter application, and the window, which provides access to functions
to affect the UI state of the window (i.e., wrapped GLFWwindow
functions).

Also provides a PluginRegistrar extension for plugins that need access
to GLFW-specific functionality.
