Add API to check for scene scoped services to initalize

[FejZa]

Reality Collective - Service Framework Pull Request

Overview

Adds overrides to the ServiceManager.WaitUntilInitializedAsync API to wait for scene scoped services to initialize.

Usage

// Works as usual and waits for the GLOBAL service manager to initialize.
await ServiceManager.WaitUntilInitializedAsync();

// Waits for the GLOBAL service manager to initialize AND services that are scoped to the game object's scene
await ServiceManager.WaitUntilInitializedAsync(gameObject.scene.name);

// Usage in Awake
private async void Awake()
{
     await ServiceManager.WaitUntilInitializedAsync(gameObject.scene.name);
    // .... services are ready
}

Changes

• Renamed the ServiceManagerInstance component and inspector to the new standard GlobalServiceManager
• Fixes: (There is no way to know whether scene services have initialized #95)
• Fixes Packages\com.realitycollective.service-framework\Runtime\AssemblyInfo.cs(9,28): error CS7034: The specified version string does not conform to the required format - major[.minor[.build[.revision]]]

Breaking Changes

• Breaking if someone is using the ServiceManagerInstance class somewhere in code, which should almost never be the case. If yes, the resolution is as simple as updating the name to GlobalServiceManager
• Breaking for the toolkit due to above reason, will update toolkit accordingly

Did not see an new editor menu option to add the scene service manager?

We should revisit the need for the assembly info files, as we did remove them from other packages. But later, let's just move on now.
