maplibre/maplibre-native ios-v7.0.0-pre2 on GitHub

Distribute a build of MapLibre iOS with the experimental C plugin API enabled as a separate Swift package, maplibre/maplibre-ios-with-plugin-api. Its MapLibre product replaces the standard one, so applications keep using import MapLibre. Plugin packages depend on its header-only MapLibrePluginApi product. Layers of plugin types appear as MLNStyleLayer in MLNStyle.layers. The GitHub release also includes a static XCFramework of this build, MapLibre.static.plugins.xcframework.zip (#4769).
Add the first version of the C plugin API for custom style layer types, with an ngon layer as example (#4612). Since then, the plugin API gained the should_animate callback (#4654), stencil overlap and near-clipped matrix options (#4665) and per-drawable depth, stencil and cull state (#4692). Plugin default colors are premultiplied (#4663) and camera-dependent plugin paint properties are reevaluated when the zoom changes (#4721).
💥 Breaking: Raise the minimum supported iOS version to 15.5, remove the filesystem polyfill, and clean up obsolete compatibility code (#4648, #4656).
Include device and simulator debug symbols in the dynamic XCFramework. The separate iOS debug-symbol ZIP is no longer published (#4698).
💥 Breaking: Replace the Mapbox.h umbrella header with MapLibre.h. MapLibre.xcframework no longer ships Mapbox.h (#4731).
Migration guide

Swift: no changes needed. Keep using import MapLibre.
Objective-C: include MapLibre.h instead of Mapbox.h:
```
// Before
#include <Mapbox.h>

// After
#include <MapLibre.h>
```
#import <MapLibre/MapLibre.h> and, with modules enabled, @import MapLibre; also work.
The MapboxVersionNumber and MapboxVersionString declarations from Mapbox.h were not carried over to MapLibre.h. These symbols were never defined in the binary, so referencing them caused a linker error. To get the SDK version at runtime, read it from the framework bundle:
```
NSString *version = [NSBundle bundleForClass:[MLNMapView class]]
                        .infoDictionary[@"CFBundleShortVersionString"];
```
```
let version = Bundle(for: MLNMapView.self)
    .infoDictionary?["CFBundleShortVersionString"] as? String
```
Export MLNPluginStyleLayer from the dynamic framework (#4731).
Export MLNBackendResource from the dynamic framework when using the Metal renderer (#4731).
Add -[MLNStyle setGlobalStateValue:forProperty:] and MLNStyle.globalState for the global-state expression and the root state property of the style (#4516).
Add the interpolate-lab and interpolate-hcl expressions (#4668).
Add rendered feature introspection. With MLNMapOptions.featureInfoEnabled, MLNRenderingStats.frameRenderedFeatures reports the features rendered by each layer and their bounds, and -[MLNMapView renderedFeatureCountForFeatureID:LayerID:SourceID:] counts them (#4460).
Size line-pattern images like MapLibre GL JS. They were drawn about 1.7× bigger and stretched along the line (#4726).
Load raster-dem tiles at the rounded zoom level, like raster sources and MapLibre GL JS (#4650).
Fix the lighting of fill-extrusion walls on rotated maps (#4662).
Fix the background layer disappearing after style changes (#4616).
Fix changes to layer transition options and the style's transition options not being applied (#4677).
Fix a crash when an image source lies wholly beyond the latitude limits of the map (#4753).
Fix a crash when querying a custom geometry source before its first tile data arrives (#4718).
Fix resetting an in-memory offline database deleting a file of the same name (#4720).
Fix the cumulative draw call count in Metal rendering statistics (#4719).
Use @autoreleasepool blocks on worker threads, so autoreleased objects such as Metal textures are released (#4621).
Make the set of available images copy-on-write, speeding up styles with many images and frequently updated sources (#4651).
