Message:

Code Modernization: Use the null coalescing operator in WP_Customize_Manager.

The four object getters in WP_Customize_Manager: get_setting(), get_panel(), get_section(), and get_control(), each spell out an isset() guard followed by return null. The null coalescing operator says the same thing in one line.

?? applies the same isset() semantics as the guard it replaces, and since the fallback here is null itself, both forms return the identical value in every case. This covers the complete set of same-shaped getters in the class.

Developed in ​https://github.com/WordPress/wordpress-develop/pull/13304.

Follow-up to r63378.

Props Soean, mukesh27.
