emulator: Implement LE advertising report

Browse Source 
When a virtual device starts a LE advertising, emulator searches for
other virtual devices that are in scan mode, in order to send adv data
to these devices.
Inverse goes when LE scan is enabled. Emulator searches virtual devices
that are in advertising mode and copy adv data to them.
