drivers: wifi: nxp: change the dormant state

1) After the wifi driver successfully connects to the AP,
the dormant state should be set to OFF.
Once a deauth/disassoc frame is received or link lost occurs,
the dormant state should be set to ON.
2) Enable CONFIG_NET_TC_SKIP_FOR_HIGH_PRIO and CONFIG_NET_CONTEXT_PRIORITY
to push high priority packets directly to network driver.
