Subject: render_widget_host_view_mac.patch

This allows Electron to override `acceptsFirstMouse` on Mac so that windows can
respond to the first mouse click in their window, which is desirable for some
kinds of utility windows. Similarly for `disableAutoHideCursor`.

Additionally, disables usage of some private APIs in MAS builds.
