Support draw debug colors on multiplayer

[ameaninglessname]

This PR does two things:

• Support draw debug colors on multiplayer
• Fix errors if AnimMan is not the default character mesh

Explanation

Changes for #240 would result in "weird sphere while play as client if show debug shapes on":

This is because AALSPlayerCameraManager::CustomCameraBehavior is not run on dedicated server, so the debug draw from server draw the initial location forever.(Initialized in AALSPlayerCameraManager::OnPossess)

This picture is showing the difference between server and client draw debug.(with some test code modification)
(I was play from current camera location, so the server location is in the air)

server sphere(left) vs client sphere (right)

Yes debug draw on server will show up in client now

see this commit of unreal b6000dafc0b07743ea859274641c551fbf03b333

you can use "show ServerDrawDebug" to toggle server debug draw.

Oh, I was doing the blueprint on ue5-main engine branch, so these change need to be re done on lower engine version to avoid blueprint can't be opened issue?

Since the PR has lots of fixes together, and assets are saved with ue5-main version, can't merge this PR at this state.

Please base the work on 4.27 and try to keep PR contents simple, otherwise it's really hard to review changes.
