Fix breaking issue with ScriptBaseUrl

[RaananW]

The general idea here is this - change the ScriptBaseUrl functionality. If it is provided AND the URL is an absolute URL that starts with cdn.babylonjs.com, change this portion of the URL with the data provided in ScriptBaseURL

Just wonder if the urls should be constructed from the constant _DefaultCdnUrl to prevent typos ?

That was the initial thought and this is why it is public, but that would force a dependency on tools right on load.
I guess most depend on tools anyhow, but it can be an optional dependency, whereas this forces it to be a required dependency.
I can make the change, as clean-code wise, it does make sense

It could also be in its own module but I guessed all the one with a url are automatically depending on tools in order to use it so I am not sure it would change anything.
