Add HVAC temp with buttons to nav bar

Created AdjustableTemperatureView class that implements the
TemperatureView interface to display temperature with buttons to
increment and decrement. Updated HvacController to only handle the
set temperature HVAC property. Removed uses of deprecated
CarHvacManager, using CarPropertyManager instead. Also modified and
updated the hvac tests.

UI changes:
- Add driver and passenger HVAC views to nav bar
- Use colored arrows with grey circle for hvac increase/decrease
