Speaking with FrSky, the main difference currently between FPORT2 and FBUS is the baud rate. This PR just adds an option for FBUS, which uses the current FPORT2 implementation, but running at the correct baud of 460800.

Pre-INAV 3.0 there were two working throttle display elements. A PR in 2.7 made a change that meant both OSD throttle elements showed the same data. This is pretty pointless. The previous method allowed the display of the throttle in a non-scaled view, which made choosing navigational throttles easier. This PR allows the pilot to see scaled throttle, unscaled, or both. Both throttles work for manual and auto throttle.

Currently, the indicator mode is only really works for quads. It doesn't make any sense for fixed wing. This PR changes that. Roll movements to the left triggers indicators on the left half of the grid. Roll movements to the right triggers indicators on the right half of the grid.

This change may also be suitable for rovers too. If so, it's an easy modification. So feedback from rover people would be great.

After asking. Around 80% of rover drivers said they turn using the roll channel. And that they would like indicators that worked as the direction input.

Rather than having a `*` prefix to indicate the PWM throttle. I'm now using the scale symbol (also used in the map) to prefix the scaled throttle. This makes a lot more sense.

Tested on other systems via HITL. All fine. Should be tested by someone with the O3 system for final confirmation.

BF does not have characters to animate the vertical bars of the artificial horizon.

This pull request will replace all the characters with the supported BF character.

The side bars won't animate, but they won't show ? either.

Clean up cmake files for SITL and fix the compilation issues caused by tooling differences between gcc and clang (used in MacOSX).

SITL on MacOSX still has lots of compile time warnings that need to be addressed and some known issues that prevent it from working with simulators, but those will be addressed in 7.0.

At this point, I don't think MacOSX SITL is ready to be added to the configurator. That should be targeted for 7.0.
