Feat: Dynamic Prefabs UIToolkit UI (Post Project Rename) [MTT-5427]

[jilfranco-unity]

Description

This is a new branch for the UI toolkit work I've been doing in PR #92 to avoid merge/filepath issues after the project folder was renamed. My UI work was purely additive at this point, so I extracted it as a unity package and added back into this branch, which is based off of develop.

Here is the copied description from that PR, with the only visual change being that the Reset Scene button has since been removed:

This is a PR for the implementation of UI toolkit for the dynamic prefabs sample. The old UI has been converted over to UI toolkit elements, and new elements to support the added functionality of the sample have been added as well. The functionality of the UI is pretty limited--this is mostly a visual and basic setup pass.

Here are some screenshots!

Main Menu:

In Game:

The values for the ClientIDs, the prefab names, and statuses are all test values, and will be subject to change.

API Buttons can be toggled on and off in the inspector to support the different needs of the different scenes!

The HostJoinUI is also intended to be very simple to extract so that we can use it in other samples moving forward!
