 * Gathers and prints information about the CPU's L3 cache.
 *
 *  This function does the following:
 *      1. Sets the cache level of interest to L3.
 *      2. Prints the following cache details to the console:
 *          - Cache level
 *          - Associativity (number of ways)
 *          - Number of physical partitions
 *          - Line size (in bytes)
 *          - Number of sets
 *          - Total cache size (in MiB), calculated using the 'get_cache_size' function.
