Tidy up Espressif ESP32 test and benchmark examples (#5800)

Tidy up Espressif ESP32 test and benchmark examples:
* add VisualGDB project and solution files for server and client
* "hardware in use revert to software" is now verbose level message
* Remove (void) TAG;  - not needed to appease compiler
* include esp_log.h lib with defined(WOLFSSL_ESPIDF)
* large ESP32 default stack size
* check for max number of arguments assembled into array
* cleanup & comments per code review
* wolfssl_test VisualGDB updates
* Espressif wolfssl_test default stack 55,000 bytes
