Forces this object to render on top of all 3d objects in the Workspace. Even if the adornment is behind a part based on its
HandleAdornment/CFrame, if AlwaysOnTop is true then the adornment will still draw on top.
The one exception to this behavior is if the `HandleAdornment/ZIndex` of the adornment is set to -1. If this is the case, the adornment will always draw behind 3d geometry.
