With this change, all the geo-to-screen conversion,
and the triangulation operations for geo polylines
and geo polygon are performed either at set time
or in the shader.
A separate bounding box geometry is processed
in the old way to provide a correct QtQuick Item
geometry, that can be used for nesting mouse areas,
performing translations, input event delivery, etc.
With this approach, performance are improved by more
than one order of magnitude in average, but complex
geometries will of course benefit more.
It also adds correct rendering support for polygons
with holes, previously only rendered correctly
by the MapboxGL plugin.
The polyline shader has basic miter joins. The miter is
skipped if the angle is too sharp to avoid complicating
the implementation.
This shader introduces some glitches when the polyline
is minified, for which the real fix is to
have LOD for the geometry, and render simplified
geometries at low zoom levels (added in a subsequent patch).
Note: this approach, at least in its current implementation,
does not support enabling layers on individual items, only
on the Map element.

This patch caches the result of geoToMapProjection() for the coordinates
of the map items, regenerating this data only upon coordinate changes.
This allows avoiding to perform a (mercator) projection basically
every time the item has to be drawn, and instead do only the wrapping
around the camera center and the projection to screen

Currently QtLocation Map items are always rendered by
QtLocation, on top of what QGeoMap generates.
This patch introduces a new private api call to QGeoMap,
supportedMapItemTypes(), that is used to inform QtLocation
to not render map items of those types, but rather
pass them over to the QGeoMap, which will take care of
the rendering.
In this way, more advanced renderers can properly render
map items, for example below labels or 3D buildings.

QtLocation quick classes and headers are moved out of the import directory.
The location quick classes are now in a subdirectory inside the main qtlocation
module.
This is necessary in order to privately export certain classes, such as
Map Items classes, and create an API to inject these objects into QGeoMap
to let plugins render the Map Items directly
