[hal, wpilib] Load joystick values upon code initialization (#4950)

During HAL_Initialize, wait up to 100ms for a DS packet to be received. Then in RobotBase, right after calling HAL_Initialize, call each language's RefreshData function to force a high level DS update. If the DS is connected, will get joystick data. If there is no data, nothing different will happen, but in that case there's no joysticks anyway.
