Fix Java-generic name-clash in AdLoadCallback subclasses (issue #1491) (#1492)

Fixes #1491.

## Problem

`AdLoadCallback<AdT>` declares `public void onAdLoaded(AdT ad)`, which erases to `onAdLoaded(Object)` in bytecode. The binding therefore only exposes `virtual OnAdLoaded(Java.Lang.Object p0)` on every concrete subclass:

- `AdManagerInterstitialAdLoadCallback`
- `InterstitialAdLoadCallback`
- `RewardedAdLoadCallback`
- `RewardedInterstitialAdLoadCallback`
- `AppOpenAd.AppOpenAdLoadCallback`

When a user overrides that in C#, the generated ACW Java stub emits `public void onAdLoaded(java.lang.Object p0)`, and javac rejects it:

```
error: name clash: onAdLoaded(Object) in MyCallback and
onAdLoaded(AdManagerInterstitialAd) in AdLoadCallback have the same
erasure, yet neither overrides the other
```

After generic substitution the parent's real method is the specialized one, so the erased override doesn't satisfy javac.

## Fix

For each concrete `*AdLoadCallback` subclass, add a specialized `onAdLoaded(SpecificAd)` method via `<add-node>` in the binding's `Transforms/Metadata.xml`. The binding now surfaces a properly-typed `virtual OnAdLoaded(SpecificAd)` with a specialized JNI registration, e.g.:

```csharp
[Register("onAdLoaded", "(Lcom/google/android/gms/ads/admanager/AdManagerInterstitialAd;)V",
          "GetOnAdLoaded_Lcom_google_android_gms_ads_admanager_AdManagerInterstitialAd_Handler")]
public virtual unsafe void OnAdLoaded(AdManagerInterstitialAd p0) { ... }
```

Users override the specialized overload, and the resulting ACW stub emits the specialized Java signature that correctly overrides the parent — matching how Google's docs show the callback being subclassed in Java.

The same fix is applied in **both** bindings that ship these types:

- `play-services-ads-lite` — `Android.Gms.Ads.*` namespace (used by `Xamarin.GooglePlayServices.Ads.Lite` direct consumers).
- `play-services-ads-api` — `Google.Android.Gms.Ads.*` namespace (pulled in transitively by `Xamarin.GooglePlayServices.Ads`, which is what the issue reporter uses).

Both `.aar`s independently contain the `*AdLoadCallback.class` files and each produces its own set of .NET types, so the metadata must be added in both places.

## Version bumps

- `Xamarin.GooglePlayServices.Ads.Lite`: `124.0.0.6` → `124.0.0.7`
- `Xamarin.GooglePlayServices.Ads.Api`: `125.4.0.1` → `125.4.0.2`
- `Xamarin.GooglePlayServices.Ads`:     `125.4.0.1` → `125.4.0.2`

## User-facing migration

Users hitting `javac.exe error JAVAC0000` from #1491 should change:

```csharp
public override void OnAdLoaded(Java.Lang.Object p0) { ... }
```

to the specialized overload, e.g.:

```csharp
public override void OnAdLoaded(AdManagerInterstitialAd p0) { ... }
```

## Verification

- `dotnet cake --target=metadata-verify` passes.
- Built both `com.google.android.gms.play-services-ads-lite` and `com.google.android.gms.play-services-ads-api` locally (against a project-referenced `Ads.Base` since the published `Ads.Base 124.0.0.1` NuGet does not yet target `net10.0-android36`) — build succeeded, 0 warnings, 0 errors.
- Verified generated `*AdLoadCallback.cs` in each project's `obj/` contains the specialized `virtual void OnAdLoaded(SpecificAd p0)` with the expected `[Register("onAdLoaded", "(Lcom/.../SpecificAd;)V", ...)]`.
- All 5 specialized overloads picked up in `PublicAPI.Unshipped.txt` for both packages by the analyzer.
