Update Fuchsia clang toolchain on Mac/Linux to goma-aware version,
tagged with `goma` in CIPD.

See:

This reverts commit 780343a2.

The previous logic allowed proxying for any view that belonged to one of the platform views' virtual displays which may lead to us allowing proxying for a view that the platform view isn't allowing proxying for, previous logic also didn't account for unattached views.

This change instead delegates the decision to the platform view.

We use the fact that each virtual display has its unique context to associate any view with its relevant virtual display.

A nice side effect of calling the platform view's checkInputConnectionProxy for webviews is that the plugin now has a way to get a handle to the ThreadedInputConnectionProxyView, which may be useful for getting keyboard working on webview's prior to Android N.

Add views that are added directly to a platform view's window as siblings to the platform view's container view, rather than as children of a full screen container.
