esp32: backport several WiFi bug fixes to v3.1

Backport following bug fixes to v3.1:

1. Bug fix of may connect to wrong AP in all channel scan

2. Station state machine change and fix ap loss

3. Add compatible to ccmp encryption

4. Update libphy.a to v3960:
   4.1 Decrease  phy_init time from 900us to 347us in sleep wakeup
   4.2 Fix RX STBC initialization
   4.3 Modify set_chan function to fix interrupt watchdog issue

5. Fix several wpa2 enterprise issues
   5.1 Fix heap corrupted bug
   5.2 Fix memory leak bug
   5.3 Make wpa2 enterprise thread-safe
   Closes https://github.com/espressif/esp-idf/issues/1569

6. Bugfix of coex wifi pm
