iOS MGLMapView missing most commits since Sept 4, 2020

[nnhubbard]

For whatever reason, it seems that mapLibre was started using an older version of mapbox-gl-native-ios. I have compared the source and it seems that none of the commits since Sept. 4, 2020 have been added in mapLibre. See:

https://github.com/mapbox/mapbox-gl-native-ios/commits/main/platform/ios/src/MGLMapView.mm

Some of these are very important such as mapbox/mapbox-gl-native-ios@8689173#diff-2b12ba2cacef0e8c6a943690a80480a938985ff758d0b69cae5913c8d3cf9273 which clearly is still buggy in mapLibre because the fix has not been merged.

Are there plans to merge all of the fixes to MGLMapView that are in the mapbox-gl-native-ios project?

The mapbox-gl-native was forked from d60fd30 - mgbl 1.6.0, mapbox-gl-native-ios from a139216 and mapbox-gl-native-android from 4c12fb2

mapbox-gl-native-ios and mapbox-gl-native-android depends on the core library (mapbox-gl-native) which was moved behind curtains by MapBox after May 7 2020 and code changes are no longer available for open-source community. So we took ios/android at the most recent version which is compatible (meaning it compiles and links) with the core library. Many commits in mapbox-gl-native-ios and mapbox-gl-native-android after this date have dependency on the core library and it is not possible simply cherry-pick them. From those with no dependency, we have cherry-picked some of them (please see the PR history) but some still remains to be cherry-picked.

Here is a list of changes which could be potentially cherry-picked.
We would welcome any help to break down these into tickets in this repo and cherry-pick them. The work is to inspect original changes, see if they were already done in MapLibre, check if the have any dependency on changes in the core library and create PR with cherry-picked changes.
