RFR: JDK-8283401: ArrayIndexOutOfBoundsException when disconnecting screen(s)

When the `D3DPipeline` is reinitialized, the adapter ordinal of all the `Screen`s are outdated.
As a consequence, when a `D3DResourceFactory` is created for a `Screen` (adapter ordinal), the code may fail with an `ArrayIndexOutOfBoundsException` as the ordinal is higher than what we would expect it to be.

Example:
We have 3 screens. Adapter ordinal 0, 1, 2.
If we now disconnect 2 screens, we only have one screen left. 
The `D3DPipeline` is reinitialized as a [D3DERR_DEVICEREMOVED](https://learn.microsoft.com/en-us/windows/win32/direct3d9/d3derr) is reported from Direct3d9.
Now the remaining screen may have the adapter ordinal 1 (from before). But since we only have 1 screen left, it should have the adapter ordinal 0. 

Direct3d9 will also return 0 as adapter ordinal if you call it. And that is what we do to update the `Screen` and fix this problem.

See also the ticket for information how to reproduce this problem (Windows only).
