Make QGeoCameraCapabilities independent of the engine

This patch makes it possible to change QGeoCameraCapabilites
at runtime, when the map type changes, to accommodate for
those plugins that offer different maps having different
capabilities.
This is then used to properly push the  min/max zoom levels
for each map type in our OSM plugin.

Autotests are included.
