Bluetooth: HID: Add support for Set Idle and Get Idle Commands 

This patch provides an interface for application to send Set Idle
and Get Idle commands to remote HID Device. Support for these
two commands was missing from exisitng code, so existing code
design is reused to add support for these two commands.
