Descrizione
While working on this PR: https://github.com/ArduPilot/ardupilot/pull/11283 I found that Guided mode's wp_bearing valueis incorrect for some submodes.
Guided uses the mode.cpp's wp_bearing method which calls the navigation library. This works when _guided_mode == Guided_WP but is incorrect when it's Guided_HeadingAndSpeed, Guided_TurnRateAndSpeed and Guided_Loiter.
We should override the wp_bearing for Guided mode and then handle these other sub modes. For example, for Guided_HeadingAndSpeed we should use the target heading. For Guided_TurnRateAndSpeed we should return 0.0f. For Guided_Loiter we should call ModeLoiter's wp_bearing.
