[TASK] port Dynamic channel selection (DCS) feature from RDKB

[kantera800]

Description

This task will be focused on porting Dynamic Channel Selection code from Intel repositories (RDKB) .

Exit criteria

• run DCS feature on RDKB platform and pass attached unitest.

• pass all prplMesh CI checks.

Detailed description

The DCS as a feature can provides information on the supported channels which can be utilized by the management system to provide better availability and user experience.

The feature is divided into two sub-features:

1. Channel Scan using NL & DWPAL Uses the DWPAL to perform a netlink channel scan to find all neighboring APs
2. Dymanic Channel Selection & Analysis Returns the Channel Scan results to provide the current status of the channels

The feature is presented in five segments each will have its own PR as follows:
