Car App library 1.7.0 - pan & zoom for maps on Android Auto / AAOS

[johan12345]

The first alpha version of Car App Library 1.7.0 was released very recently. This might allow us to make improvements on some long-standing issues:

• The new MapWithContentTemplate is now available starting with Car API level 7. This seems to finally make it possible to pan and zoom the map (Android Auto/Automotive: Pan and zoom the map #184). We'll have to check whether that feature is already implemented in the host apps (Android Auto app & AAOS Template Host).
• It should fix the common crash "java.lang.IllegalArgumentException: Invalid speed unit: 0" on some Volvo/Polestar cars (diff, issue)

The new MapWithContentTemplate seems to be a bit more effort to implement than expected, as it requires us to render the map ourselves. For that we will be using Mapbox/OSM - Google Maps is not available, at least not on AAOS.

The upside is that rendering the map ourselves (which was previously not possible for POI apps) gives us a lot more flexibility, e.g. with how we display markers on the map etc. - so we could make it work a lot more like in the phone app.
With some refactoring, we could probably reuse some of the marker handling code that we have already implemented for the phone app.

To do:

• Implement place search
• Shift the focus on the map a bit more to the right (based on the visibleArea) so that the current location is shown in the center of the visible area
• Debug zooming with focus point (currently disabled, we always zoom towards the center)
• Test on Android Auto
• Try if we can use Google Maps on Android Auto, currently it's hardcoded to MapLibre
