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

+# Espressif Updates
+
+See [#5795]()
+
+## 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

+## Performance
+
+Reminder than when building on WSL in `/mnt/c` there will be a noticeable performance degradation at compile time. Using `~/` will be faster at the cost of shared filesystems.
+
+Example build on WSL:
+
+```
+Optionally install wolfSSL component
+# cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF
+./setup.sh
+
+cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF/examples/wolfssl_benchmark
+
+# Pick ESP-IDF install directory, this one for v4.4.2 in VisualGDB
+. /mnt/c/SysGCC/esp32/esp-idf/v4.4.2/export.sh
+
+
+idf.py build flash -p /dev/ttyS20 -b 921600 monitor
+```
+
+## Example Output
+
+Note the default wolfSSL `user_settings.h` is configured by default to be the most 
+compatible across the widest ranges of targets. Contact wolfSSL at support@wolfssl.com
+for help in optimizing for your particular application, or see the 
+[docs](https://www.wolfssl.com/documentation/manuals/wolfssl/index.html).
+
+Compiled and flashed with `idf.py build  flash -p /dev/ttyS7 -b 921600 monitor`:

 # wolfSSL Crypt Test Example
 
-The Example contains of wolfSSL test program.
+The Example contains of wolfSSL benchmark program.
+
+1. `idf.py menuconfig` to configure the program.  
+    1-1. Example Configuration ->
+
+    BENCH_ARG : argument that you want to use. Default is "-lng 0"  
+    The list of argument can be find in help.
 
 When you want to run the benchmark program
-1. `idf.py menuconfig` to configure the program,first
-2. `idf.py build` to compile and `idf.py -p <PORT> flash` to load the firmware
-3. `idf.py monitor` to see the message
+
+1. `idf.py -p <PORT> flash` to compile and load the firmware
+2. `idf.py monitor` to see the message
 
 See the README.md file in the upper level 'examples' directory for more information about examples.
+
+Reminder than when building on WSL in `/mnt/c` there will be a noticeable performance degradation at compile time. Using `~/` will be faster at the cost of shared filesystems.
+
+Example build on WSL, assuming `git clone` from `c:\workspace`:
+
+```
+# Optionally install wolfSSL component
+# cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF
+./setup.sh
+
+# switch to test example
+cd /mnt/c/workspace/wolfssl/IDE/Espressif/ESP-IDF/examples/wolfssl_test
+
+# Pick ESP-IDF install directory, this one for v4.4.2 in VisualGDB
+. /mnt/c/SysGCC/esp32/esp-idf/v4.4.2/export.sh
+
+# build and flash, in this example to COM20
+idf.py build flash -p /dev/ttyS20 -b 921600 monitor
+```
+
+## Example Output
+
+Note the default wolfSSL `user_settings.h` is configured by default to be the most 
+compatible across the widest ranges of targets. Contact wolfSSL at support@wolfssl.com
+for help in optimizing for your particular application, or see the 
+[docs](https://www.wolfssl.com/documentation/manuals/wolfssl/index.html).
+
+Compiled and flashed with `idf.py build  flash -p /dev/ttyS7 -b 921600 monitor`:
