esp_supplicant_disable_pmk_caching() function

Disable or enable the caching of Pairwise Master Keys (PMK) in the supplicant. This function allows disabling or enabling the caching of Pairwise Master Keys (PMK). PMK caching is used in Wi-Fi Protected Access (WPA/WPA2/WPA3) networks to speed up the reconnection process by storing the PMK generated during the initial connection. Disabling PMK caching may result in slightly longer reconnection times. PMK caching is enabled by default, this configuration has been provided in case the AP is known not to support PMK caching or has a buggy implementation for PMK caching.
