Added a new test to verify UI navigation and submit actions using a gamepad when the event system's playerRoot (localMultiPlayerRoot) is set and when it is null. Ensures navigation and submit functionality work correctly in both scenarios.

Description
Case ISXB-1610] (https://issuetracker.unity3d.com/product/unity/issues/guid/ISXB-1610)
This PR removes the null check in MultiplayerEventSystem.InitializePlayerRoot() that prevented setting InputSystemUIInputModule.localMultiPlayerRoot to null. We found that the check was introduced in PR #1547, but no specific reason was provided
Since localMultiPlayerRoot is already safely used (e.g., in IsMoveAllowed() via its own null check), we have removed the null check.
Testing status & QA
Added a UnityTest to validate that setting InputSystemUIInputModule.localMultiPlayerRoot to null allows full UI navigation as expected.
Overall Product Risks
Please rate the potential complexity and halo effect from low to high for the reviewers. Note down potential risks to specific Editor branches if any.
Comments to reviewers
As localMultiPlayerRoot is having its own null check, we have removed the PlayerRoot null check in InitializePlayerRoot().
