fix: Remove Arduino entry points

Improved flexibility by removing the Arduino entry points in favor of manual calls to setup/loop that the user can call from their entry point.  This is the more common use case for Arudino.

Also added the gtest/gmock_main files to the PlatformIO ignore list since we are not supporting that feature.
