Add external output support (#3)

The eom API only supports elm_win. So TizenWindowElementary supports this. Currently, only HDMI type is available. It can be extended according to the requirements. https://docs.tizen.org/application/native/guides/device/ext-output/ +) How to map input device.(in sdb shell) 1. Check to input event node. $) winfo -input_devices 2. Set to input and output event node $) winfo -input_output_set [input(ex./dev/input/eventX)] [output(ex.HDMIA-1)] related pr : flutter-tizen/flutter-tizen#465 Co-authored-by: Swift Kim <[email protected]>
