controller_vhci_ble_adv example on ESP32-C6 linking errors (IDFGH-13073)

Answers checklist.

[X] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
[X] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
[X] I have searched the issue tracker for a similar issue and not found a similar issue.
IDF version.

v5.2-dev-3065-g272b4091f1
Operating System used.

macOS
How did you build your project?

Command line with idf.py
If you are using Windows, please specify command line type.

None
What is the expected behavior?

The example should compile for ESP32-C6
What is the actual behavior?

It fails to compile due to missing symbols:
undefined reference to `esp_vhci_host_send_packet'
undefined reference to `esp_vhci_host_register_callback'
others
Steps to reproduce.

Go to /examples/bluetooth/hci/controller_vhci_ble_adv
idf.py set-target esp32-c6
idf.py build

➜  controller_vhci_ble_adv git:(master) ✗
More Information.

This is the same issue as https://github.com/espressif/esp-idf/issues/12194 However, the original poster had to patch esp-idf & his code locally to work around.
The main issue here is that the VHCI Interface gets disabled without CONFIG_BT_BLUEDROID_ENABLED. The VHCI interface is very important to allow for alternative Bluetooth stacks, e.g. our BTstack, to successfully run on all ESP32 variants that contain a Bluetooth Controller.
Please enabled the VHCI interface for the C6 as it was done for ESP32, ESP32-C3, ESP32-S3,...
Thanks!
