[PATCH 09/11] client: Add Channel Sounding ranging data mode control

[Cheng Jiang <cheng.jiang@oss.qualcomm.com>]

Add a "ranging-data-mode" command to the Channel Sounding submenu that
selects how Ranging Data is received from a peer (disabled, real-time or
on-demand) and the CCCD transport (notify or indicate), invoking the
ChannelSounding1.SetRangingDataMode method on the device.

Add an advertising helper so the Responder can advertise the Ranging
Service UUID for discovery, together with a getter for the default
LEAdvertisingManager proxy it needs.
