Clean up include dependencies in public headers

Removing includes which were not needed by headers
Note that if you include those headers directly (instead of including irrlicht.h) you may have to add some new includes now.
Thought I generally tried to avoid removing headers where it leads to too much changes in user-code
Reason was mainly that IntelliSense in VisualStudio 17.7 added a new feature which shows those unused headers :)
Has to be used a bit careful as it doesn't know about defines and other platforms
And I only did clean up public headers so far (will probably do some more later or another time)
