Change pristine build option

The pristine build mode indicated if the build folder must be clean before each build.

To change the pristine build option mode, right-click on the application > Configure > Change Pristine Build then select the option mode:

• auto: The west build command auto-detects situations when build directory needs to be made clean.
• always: Always clean the build directory before build
• never: No attempt to detect if build directory needs to be made clean before build.
