Plumb ShowEmojiPanel call through to app shim process on Mac

This CL moves the call to ui::ShowEmojiPanel from the browser process
to the app shim process for PWA windows on Mac via the following path:

RenderViewContextMenu::ExecuteCommand -> BrowserWindow/BrowserView -> Widget -> NativeWidgetMac --mojo--> BridgedNativeWidget/BridgedNativeWidgetImpl -> ui::ShowEmojiPanel()

All other platforms will continue to call ui::ShowEmojiPanel() from
the browser process.

This fixes the "Emoji & Symbols" context menu entry for PWA
text fields (in views and the web) on Mac.
