feat: dedicated game server sample - upgrade to multiplayer services sdk [MTT-11329]

Description

This PR integrates the Multiplayer SDK to the Dedicated Game Server Sample.
Introduced are a few key changes to the sample's workflow. There are now 4 new Play Mode Scenarios:

• EditorAsClient: One Virtual Player is Server and autoconnects with IP. Editor and all other Virtual Players are Clients that autoconnect with IP.
• EditorAsServer: Editor is Server and autoconnects with IP. All Virtual Players are Clients that autoconnect with IP.
• DeployToUGS: Deploys a remote instance of a build to a fleet defined inside your environment.
• Live: All Virtual Players are Clients.

The first 2 are meant to server as quick feature validation scenarios, using direct IP connection. DeployToUGS deploys a build to the user's Cloud environment, where they are able to validate a server being allocated -- once allocated, they are able to connect via Direct IP, as shown in the Play Mode Status Window. The last, Live, validates the live workflow, where each client connects through the UI, with sessions/matchamaker tickets.

To validate the PR, go through each play mode scenario, making sure you switch to the appropriate build profile in the Editor.

There's a lot of changes in this PR that do not seem related to its scope. I see changes in Starter assets, prefabs and sounds. Are these changes on purpose, or were they pushed by mistake?

There's a lot of changes in this PR that do not seem related to its scope. I see changes in Starter assets, prefabs and sounds. Are these changes on purpose, or were they pushed by mistake?

I did update packages to the latest recommended version, and that included Starter Assets, so its packaged assets were updated.
I could split those out as individual PRs if you'd like. But since NGO components were upgraded, it was nice to have those changes included in one go with the art side of changes.
