HID: Added new API to send RC key eventssubmit/tizen/20160704.015035accepted/tizen/wearable/20160705.003600accepted/tizen/tv/20160705.003621accepted/tizen/mobile/20160705.003539accepted/tizen/ivi/20160705.003641accepted/tizen/common/20160704.145416

This patch adds API to send RC key event to remote device.
It also adds new test case to demonstarte usage of added API.
