feat(esp_wifi): Showcase roaming_app capabalities through dedicated example

Browse Source 
- Shows use of roaming app through dedicated example : roaming_app_example.
- Changes the location of the earlier roaming example by moving it into the roaming_11kvr.
- Please note that this feature is still experimental and still being optimised
and tuned.

# Roaming Example
# Wi-Fi Roaming Examples
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This directory contains 2 example ESP-IDF projects that demonstrate the Wi-Fi Roaming capabilities. These are intended to demonstrate the Wi-Fi roaming functionality, and to provide code that you can copy and use in your own projects.
This example demonstrate a roaming example using 11k and 11v APIs.
# Example Layout
## How to use example
* `roaming_11kvr` demonstrates the use of API's that implement IEEE 802.11kvr mechanisms.
* `roaming_app` implements Espressif's roaming app that optimally combines legacy roaming and 802.11kv based
roaming for effective roaming.
Before project configuration and build, be sure to set the correct chip target using `idf.py set-target <chip_name>`.
# More
### Hardware Required
* A development board with ESP32/ESP32-S2/ESP32-C3 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
* A USB cable for Power supply and programming
### Build and Flash
Build the project and flash it to the board, then run the monitor tool to view the serial output:
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.

# Wi-Fi Station Example
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This example shows how to use the Wi-Fi Roaming App functionality of the Wi-Fi driver of ESP for efficient roaming between compatible APs.
## How to use example
### Configure the project
Open the project configuration menu (`idf.py menuconfig`).
In the `Example Configuration` menu:
* Set the Wi-Fi configuration.
* Set `WiFi SSID`.
* Set `WiFi Password`.
* To better understand how to configure the app in Components --> Wi-Fi --> Roaming App settings,
please go read the README at components/esp_wifi/wifi_apps/roaming_app/src.
Optional: If you need, change the other options according to your requirements.
### Build and Flash
Build the project and flash it to the board, then run the monitor tool to view the serial output:
Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.
(To exit the serial monitor, type ``Ctrl-]``.)
See the Getting Started Guide for all the steps to configure and use the ESP-IDF to build projects.
