Marius Vikhammer c63684cf6c hw crypto: activated hardware acceleration for esp32s2beta
Activated AES, RSA and SHA hardware acceleration for esp32s2 and enabled related unit tests.

Updated with changes made for ESP32 from 0a04034, 961f59f and caea288.

Added performance targets for esp32s2beta

Closes IDF-757
