[RFC] doc/advertising-api: Add Flags property

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This adds Flags which the application can use in case it want to set
it own flags.

Note: This would allow for example an application to advertise as
discoverable even if the adapter is not discoverable which may be
required by dual-mode as it may not require BR/EDR to be discoverable.
