Mark a function as deprecated and inform when it has been used.

There is a {@see 'hook deprecated_function_run'} that will be called that can be used to get the backtrace up to what file and function called the deprecated function.

The current behavior is to trigger a user error if WP_DEBUG is true.

This function is to be used in every function that is deprecated.
