[PATCH BlueZ v1 0/5] Add D-Bus and bluetoothctl support for Channel Sounding control

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

This series adds user-facing control and configuration support for
Bluetooth LE Channel Sounding (CS) through a new D-Bus interface and
bluetoothctl integration.

The RAP profile is extended to expose an
org.bluez.ChannelSounding1 interface, allowing external applications
to configure default Channel Sounding settings and start or stop
measurement procedures. CS configuration, frequency, and default
settings are moved from hardcoded values into shared parameter
structures and accessor APIs, enabling runtime configuration from the
D-Bus layer.

To make the new functionality accessible from the command line,
bluetoothctl gains a dedicated "cs" submenu for configuring parameters,
starting and stopping measurements, and monitoring active sessions.

The series also ensures the Channel Sounding interface is available on
reflector devices by registering relevant GATT profiles even when GATT
client discovery is skipped, and updates the D-Bus documentation with
usage examples and bluetoothctl references.

Patch summary:
  1. rap: Add Channel Sounding parameter types and APIs
  2. profiles: Add D-Bus Channel Sounding control API
  3. src: Register GATT profiles for Channel Sounding reflector
  4. doc/org.bluez.ChannelSounding1: Add Used by reference and examples
  5. client: Add Channel Sounding shell submenu

This enables end-to-end Channel Sounding control through both D-Bus
clients and bluetoothctl while keeping measurement state synchronized
with controller procedure status
