[PATCH BlueZ v1 1/3] rap: Add OndemandRanging configuration option

[Naga Bhavani Akella <naga.akella@oss.qualcomm.com>]

Add a per-adapter config knob under [ChannelSounding] to let the RAS
Initiator use on-demand Ranging Data delivery (Get_Ranging_Data/
ACK_Ranging_Data) instead of real-time notifications. Defaults to
false.

- src/btd.h: add bool ondemand_ranging to struct btd_le_bcs.
- src/main.c: parse "OndemandRanging" into
  btd_opts.defaults.bcs.ondemand_ranging.
- src/main.conf: document the new option.
