samples: bluetooth: Add Channel Classification sample

This sample demonstrates a usecase for channel classification.
The sample shows the central receiving channel classification reports
from the peripheral and applying them in a channel map update.

+   :title: Bluetooth: Channel Classification
+
+This sample demonstrates LE Channel Classification reporting between a central and a peripheral.
+
+Requirements
+************
+
+The sample supports the following development kits:
+
+.. table-from-sample-yaml::
+
+You can use any combination of the development kits mentioned above in your testing setup.
+
+Additionally, the sample requires a connection to a computer with a serial terminal for each of the development kits.
+
+Overview
+********
+
+When connected, the peripheral cycles through predefined host channel maps, changing every five seconds.
+
+The central enables channel classification reporting using :c:func:`hci_vs_sdc_channel_reporting_enable` and handles the received reports in a local HCI VS event callback.
+
+Building and running
+********************
+
+.. |sample path| replace:: :file:`samples/bluetooth/channel_classification`
+
+.. include:: /includes/build_and_run.txt
+
+.. |sample_or_app| replace:: sample
+.. |ipc_radio_dir| replace:: :file:`sysbuild/ipc_radio`
+
+.. include:: /includes/ipc_radio_conf.txt
+
+Testing
+=======
+
+After programming the sample to both development kits, test it by performing the following steps:
+
+1. Connect to both kits with a terminal emulator (for example, the `Serial Terminal app`_).
+   See :ref:`test_and_optimize` for the required settings and steps.
+#. Reset both kits.
+#. In one of the terminal emulators, type ``c`` to start the application on the connected board in the central role.
+#. In the other terminal emulator, type ``p`` to start the application in the peripheral role.
+#. Observe that the kits establish a connection.
+#. On the peripheral, observe a new channel map printed every five seconds.
+#. On the central, observe matching channel maps applied from the received classification reports.
