Support mesh intersection for camera orbit (#982)

Browse Source 
* wip support for mesh intersection with intersector bus

* WIP camera mesh intersection orbit logic

* remove unneeded template argument

* add bus connect/disconnect

* fix intersection logic

* small updates, additional comments, some tidy-up

* update formatting options slightly

* use aznumeric_cast

* temp workaround for negative distances with RayIntersection
