Can't animate moving `MapViewAnnotation`

Nobody has claimed this yet.

## Observed behavior and steps to reproduce

Changing the `coordinate` of a `MapViewAnnotation` via `withAnimation` causes the view to **re-appear** instead of **moving** to the new location.

```swift
import SwiftUI
@_spi(Experimental) import MapboxMaps

struct MapboxMapView: View {
private let position = Viewport.camera(
center: .londonA,
zoom: 16
)
@State var curLocation: CLLocationCoordinate2D = .londonA

var body: some View {
Map(initialViewport: position) {
MapViewAnnotation(coordinate: curLocation) {
Circle()
}
}
.ignoresSafeArea()
.overlay(alignment: . bottomTrailing) {
Button("Change location") {
withAnimation {
curLocation = .londonB // SHOULD CAUSE THE ANNOTATION TO MOVE, NOT RE-APPEAR
}
}
}
}
}

extension CLLocationCoordinate2D {
static let londonA = CLLocationCoordinate2D(
latitude: 51.507222,
longitude: -0.1275
)

static let londonB = CLLocationCoordinate2D(
latitude: 51.508222,
longitude: -0.1276
)
}
```

## Expected behavior

The annotation should **move** to the new location.

## Notes / preliminary analysis

Seems to have been possible in [UIKit examples](https://github.com/mapbox/mapbox-maps-ios/blob/9dafb886f53d01753ee08cbaba2011b6612fa37f/Apps/Examples/Examples/All%20Examples/Annotations/ViewAnnotationAnimationExample.swift#L98) but the behavior seems different in SwiftUI.

Start by running the SwiftUI reproduction with MapViewAnnotation and compare its behavior with the UIKit ViewAnnotationAnimationExample linked in the issue. Trace how the SwiftUI annotation responds to coordinate changes under withAnimation; done means the annotation moves smoothly to londonB rather than disappearing and reappearing.
