[SDK-1001] Add consent debug settings support

[Khrolovich]

Adds ConsentManager.Instance.SetDebugSettings(ConsentDebugSettings) so a publisher can force the consent geography on a registered test device, mirroring the native ConsentDebugSettings API added in Appodeal Android SDK 4.4.0 (AppodealSDK#3335) and StackConsentManager-iOS 4.2.0 (StackConsentManager-iOS#49).

Jira: SDK-1001

API

ConsentManager.Instance.SetDebugSettings(new ConsentDebugSettings
{
    Geography = ConsentDebugGeography.Eea,           // Eea | RegulatedUsState | Other
    TestDeviceIds = new List<string> { "<id from the native log>" }
});
ConsentManager.Instance.RequestConsentInfoUpdate(parameters);

SetDebugSettings(null) clears the override. The gate (debuggable build + emulator/simulator or registered device id) and the log hints live in the native SDKs; the plugin only marshals the values.

Platform mapping

Platform	Bridge
Android	AndroidCmpJavaHelper.GetConsentDebugSettingsJavaObject builds com.appodeal.consent.ConsentDebugSettings(ConsentDebugGeography, java.util.ArrayList) and calls the static ConsentManager.setDebugSettings; null clears
iOS	CMPUnityPluginConsentManagerSetDebugSettings(int geography, const char* testDeviceIds) maps the enum index to APDConsentDebugGeography and splits the comma-joined ids; -1 clears
Editor	no-op with a log line
Dummy	unsupported-platform warning, as for the other methods

Release binding

• package.json: version 2.2.0, com.appodeal.mediation 4.4.0. The mediation 4.4.0 release is what pulls Appodeal Android 4.4.0 and Appodeal iOS 4.4.0 (with the StackConsentManager 4.2.0 pin), so this package must not be published before it.
• CHANGELOG date is left as TBD until the release date is known.

Verification

• Unity 2022.3 project with this branch and the mediation plugin pointed at locally built natives (Android core:4.4.0 from mavenLocal, StackConsentManager 4.2.0 xcframework from PR #49).
• Android: development APK contains the ConsentManager.setDebugSettings call and the sample's SetDebugSettings in the IL2CPP metadata; iOS: device build links the local framework.
• Manual publisher flow (run with an empty list, register the printed id, rebuild, consent form appears under a non-EEA VPN) on physical devices for both platforms.
