Allows spiram malloc with wifi dynamic buffers - better free heap (#5791)

Browse Source 
Summary

Modifies WiFi lib to allow dynamic buffer allocation along with SPIRAM MALLOC enabled
This gives more heap space to the users

Related PR in Arduino Lib Builder: espressif/esp32-arduino-lib-builder#47

Impact

WiFi will work the same as it was in version 1.0.6, restoring free heap.
