Add debug vesion unit tests steps in document (#165)

* Add debug version unit tests steps
  * Unit tests could use AWS SDK dlls on Windows instead of
    static linking to AWS SDK libraries

 # Building the AWS SDK for C++
 The driver supports AWS IAM and AWS Secrets Manager authentication by using [AWS SDK for C++](https://docs.aws.amazon.com/sdk-for-cpp/). The driver requires `aws-cpp-sdk-core`, `aws-cpp-sdk-rds`, and `aws-cpp-sdk-secretsmanager`. You can either build the SDK yourself directly from the source using the script under `scripts` folder or [download the libraries using a package manager](https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/sdk-from-pm.html). The script will install the SDK under `aws_sdk/install` folder. The driver will look for SDK dependencies through `aws_sdk/install` folder and `CMAKE_PREFIX_PATH` environment variable.
-> **_NOTE:_** On Winodws, depending on the use case, you may build the SDK as a static library or dynamic library. On Linux and macOS, you should always build the SDK as a dynamic library.
+> **_NOTE:_** On Windows, depending on the use case, you may build the SDK as a static library or dynamic library. On Linux and macOS, you should always build the SDK as a dynamic library.
 
 ## Windows
-If you want to build and run the driver unit tests, you need to build the SDK as static library, as the unit test binary will link every dependency statically.
+### For release version unit tests or driver
 ```
-.\scripts\build_aws_sdk_win.ps1 x64 Debug OFF "Visual Studio 16 2019"
+.\scripts\build_aws_sdk_win.ps1 x64 Release ON "Visual Studio 16 2019"
 ```
-If you want to build the driver DLL, you need to build the SDK as dynamic library, as the driver DLL will link the SDK dynamically.
+### For debug version unit tests

 ## Unit Tests
 1. Build driver binaries with `ENABLE_UNIT_TESTS` command set to `TRUE`:
    - **Windows**
+
+       Add AWS SDK dynamic libraries path to environment variable `path` so the dlls could be found when unit tests are running.
+
+     - For release version unit tests, run the following command from repository root
         ```
         cmake -S . -B build -G "Visual Studio 16 2019" -DMYSQL_DIR="C:\Program Files\MySQL\MySQL Server 8.0" -DMYSQLCLIENT_STATIC_LINKING=TRUE -DENABLE_UNIT_TESTS=TRUE
         cmake --build build --config Release
         ```
+     - For debug version unit tests
+
+       - Download MySQL debug binaries from [MySQL::Download MySQL Community Server](https://dev.mysql.com/downloads/mysql/).
+
+       - Extract the `mysqlclient.lib` from debug binaries. Make sure to backup your release version of mysqlclient.lib in `MYSQL_DIR\lib`, e.g. `C:\Program Files\MySQL\MySQL Server 8.0\lib`. Replace release version `mysqlclient.lib` with debug version of `mysqlclient.lib`.
+       - Run the following command from repository root
+
+        ```
+        cmake -S . -B build -G "Visual Studio 16 2019" -DMYSQL_DIR="C:\Program Files\MySQL\MySQL Server 8.0" -DMYSQLCLIENT_STATIC_LINKING=TRUE -DENABLE_UNIT_TESTS=TRUE -DCMAKE_BUILD_TYPE=Debug
+        cmake --build build --config Debug
+        ```
    - **MacOS**
+      - Run the following command from repository root 
         ```
         cmake -S . -B build -G "Unix Makefiles" -DMYSQLCLIENT_STATIC_LINKING=true -DODBC_INCLUDES=/usr/local/Cellar/libiodbc/3.52.15/include -DENABLE_UNIT_TESTS=TRUE
         cmake --build build --config Release
         ```
    - **Linux**
+      - Run the following command from repository root
         ```
         cmake -S . -B build -G "Unix Makefiles" -DMYSQLCLIENT_STATIC_LINKING=true -DWITH_UNIXODBC=1 -DENABLE_UNIT_TESTS=TRUE
