Wi-Fi PSK routine could be optimized further (IDFGH-14279)

[ivq]

Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

Wi-Fi PSK is vital for WPA/WPA2 Personal networks, and its calculation is a heavy load.
Currently, we have fast-pbkdf2, but the performance of it is far from optimal.
Optimizing PSK routine brings many benefit. For one thing, it reduces time spent to join an AP. For another, it improves
responsiveness of the Wi-Fi stack as the Wi-Fi task calls the routine.

Proposed improvement

I'm working on an optimized PSK implementation: #15073 and it is showing significant improvement. See the table below.

Chip	fast-pbkdf2	My impl
ESP32	138	x
ESP32S2	158	72
ESP32S3	284	71
ESP32C2	189	143
ESP32C3	211	83
ESP32C6	244	150

The numbers are milliseconds spent to calculate a PSK. x means not supported currently.
The benchmark is run based on the wifi/iperf example with default SDK config.
