Changes in November 2022

Updates to Espressif ESP-IDF wolfssl_benchmark and wolfssl_test examples:

Benchmark example no longer runs tests.
Fixed Test example that was missing code files. (no longer installed locally)
Rename benchmark/main and test/main filenames from helper.c to main.c, cleaned up.
Added main.h
Revised main/CMakeLists.txt to use only main.c
Set components main and wolfssl for project CMakeLists.txt
Update wolfcrypt esp32_sha.c and sha256.c to now report unexpected reentry as verbose log rather than error message.
wolfcrypt/test.c now returns args.return_code when WOLFSSL_ESPIDF is defined.
wolfcrypt/test.h now declares int wolf_test_task(void) when WOLFSSL_ESPIDF is defined.
setup.sh no longer copies benchmark.c(.h) to local project directory.
Added libs/Tigard.cfg file for Tigard JTAG debugger.
Update sdkconfig.defaults with compiler optimizations and stack check.
Added VisualGDB Project file & Visual Studio solution file.
Added optional time_helper for wolfssl_test
Exclude ssl_misc.c in component cmake to fix warning: #warning ssl_misc.c does not need to be compiled separately from ssl.c
