[1.190.101][ModAPI] IMyCubeBlock.ResourceSink is broken

It seems that the ResourceSink property from IMyCubeBlock is not really assigned properly internally... some blocks have it, some don't, making it quite misleading and unreliable.

I suggest having it as an abstract method on the base that simply returns Components.Get<MyResourceSinkComponent>() and thrusters override it to return their shared sink instead.

Steps to reproduce, with thrusters in particular:

1. Create a local mod for script:

using Sandbox.Common.ObjectBuilders;
using Sandbox.Game.EntityComponents;
using Sandbox.ModAPI;
using VRage.Game.Components;
using VRage.Game.ModAPI;
using VRage.ModAPI;
using VRage.ObjectBuilders;

namespace BugReport
{
    [MyEntityComponentDescriptor(typeof(MyObjectBuilder_Thrust), false)]
    public class BugReport_ResourceSinkThrust : MyGameLogicComponent
    {
        public override void Init(MyObjectBuilder_EntityBase objectBuilder)
        {
            NeedsUpdate = MyEntityUpdateEnum.EACH_FRAME;
        }

        public override void UpdateAfterSimulation()
        {
            var block = (IMyCubeBlock)Entity;
            var sink = block.Components.Get<MyResourceSinkComponent>();

            MyAPIGateway.Utilities.ShowNotification($"ResourceSink={block.ResourceSink != null}; Components.Get<Sink>()={sink != null}", 16);
        }
    }
}

2. Create an empty world with that local mod.

3. Place 2+ thrusters of same type on the same grid.

It will show that ResourceSink is null on all of them while the components.Get one is not null only on one.
