Remove compile time dependency on GMS

[link2xt]

Follow-up to #2349, runtime dependency and non-free components are removed, but GMS is still downloaded during the build.

See https://gitlab.com/fdroid/fdroiddata/-/merge_requests/11527#note_1053804549

A quick solution to get DeltaChat to F-Droid is to use a patched version of mapbox-events-android, like here:
ev-map/EVMap@ed80d7b
Patched version is at https://github.com/johan12345/mapbox-events-android

Proper solution is to upstream fixes to MapLibre and introduce a free build flavour, suggested at https://gitlab.com/fdroid/fdroiddata/-/merge_requests/11527#note_1053885392

I suggest that we

1. Fork version with a fix https://github.com/johan12345/mapbox-events-android into deltachat org.
2. Use forked version similarly to ev-map/EVMap@ed80d7b (via https://www.jitpack.io ?)
3. Check that GMS is no longer referenced and downloaded at all.
4. Release a new version and get it into F-Droid.

Assign the issue to self if you are going to do it.

Then keep this issue until the fix is upstreamed to MapLibre so we don't have to maintain a fork.

There is a https://gitlab.com/fdroid/fdroiddata/-/merge_requests/11532 that already works for me.

maplibre 10 is out for a while now, plans to update?

I have tried to make an update at #2542, but MapLibre 10 breaks Android 4 support. Filed an upstream bugreport at maplibre/maplibre-native#1010

since MapLibre 10 breaks support for Android 4 and it seems they can't bring it back lower than API level 18 anyway because their needs, so this issue can be closed also because meanwhile the issue is solved by fdroid somehow, any advancements in this area will be with the complete removal of MapLibre, not upgrading it, the path to follow will probably be similar to what DC iOS is planning: https://github.com/deltachat/deltachat-ios/pull/1912
