Introduce new macros to improve debugging capabilities in F1AP library

* _F1_EQ_CHECK_GENERIC can be used to check the equality of two different members of F1AP structs and return `false` if the condition is not met. When the condition fails, the macros will print a debug message to the standard error stream, including the function name, line number, and the provided format string and arguments.
