Allow Mapbox or MapLibre from SPM on iOS, and different libs on android

[mfazekas]

Description

This PR allows to specify the Mapbox library to be consumed via SwiftPackageManager. This means MapLibre for example can be used instead of Mapbox.

Fixes #1273

Podfile:

$RNMBGL_Use_SPM = {
  url: "https://github.com/maplibre/maplibre-gl-native-distribution",
  requirement: {
    kind: "upToNextMajorVersion",
    minimumVersion: "5.11.0"
  },
  product_name: "Mapbox"
}


pre_install do |installer|
  $RNMBGL.pre_install(installer)
end
...

post_install do |installer|
   flipper_post_install(installer)
   $RNMBGL.post_install(installer)
end

Top level build.gradle:

buildscript {
    ext {
   ...
         rnmbglMapboxLibs = {
             implementation ("org.maplibre.gl:android-sdk:9.2.1")
             implementation ("com.mapbox.mapboxsdk:mapbox-sdk-turf:5.3.0")
         }

         rnmbglMapboxPlugins = {
             implementation ("com.mapbox.mapboxsdk:mapbox-android-gestures:0.7.0")
             implementation ("com.mapbox.mapboxsdk:mapbox-android-plugin-localization-v9:0.12.0")    {
                 exclude group: 'com.mapbox.mapboxsdk', module: 'mapbox-android-sdk'
             }
             implementation ("com.mapbox.mapboxsdk:mapbox-android-plugin-annotation-v9:0.8.0")        {
                 exclude group: 'com.mapbox.mapboxsdk', module: 'mapbox-android-sdk'
             }
             implementation ("com.mapbox.mapboxsdk:mapbox-android-plugin-markerview-v9:0.4.0") {
                 exclude group: 'com.mapbox.mapboxsdk', module: 'mapbox-android-sdk'
              }
         }
}

Thanks

Can't we move rnmbglMapboxLibs and rnmbglMapboxPlugins in some form of constant, you know have one place to change it.

Also, is this the recommended way to have variable dependencies?
Not gonna complain, just feels kinda hacky :D

[mfazekas]

@ferdicus sorry I'm not really familiar with groovy and/or gradle. This is what I could came up with. I've seen rootProject.ext.get/rootProject.ext.has in other projects (example)

[ferdicus]

Why do we need this here, when we have it in the Podfile, or why have it there if it's here?
I'd assume you want to extract it from the Podfile to make it more user editable?

[mfazekas]

Currently we also support $RNMBGL_Use_SPM = true to use Maplibre from spm with those default params. Not sure if that's desired/or good idea.

[ferdicus]

Maybe we should be opinionated towards one?
Configuration is cool and all, however I feel like the install steps are already confusing to some user.

WDYT?

[mfazekas]

For the short term I think this is for advanced users.

Later we can consider defaulting to MapLibre as It doesn't require the access token dance.

@mfazekas , also let me know, when you're done with this - I can assist with the README/ Installation guides/ Changelog and test a bit

[mfazekas]

@ferdicus I'm done with the PR

Cool, thanks for this - I'll try to test this in the coming days. 👍🏿
