Change naming in some platform files

[TimSylvester]

Eliminates some additional vestiges of Mapbox.

Fixes a problem with debug tile outlines caused by each source clearing debug drawables from previous sources. This appeared because the change from "com.mapbox" to "org.maplibre" makes the annotation source appear after the "maplibre" source specified in the test stylesheet. Note that this will cause multiple debug features to appear when the same tiles are rendered from multiple sources.

Also fixes missing UBO binding on polyline debug outlines. This was probably working only because the UBO isn't ever accessed (expressions aren't used in debug drawables), and the error only appears with Metal validation enabled.
