Move implementation private files from com.jogamp.<module>.impl. to jogamp.<module> (1/2) - rename task

- com.jogamp.opengl.impl                     -> jogamp.opengl
- com.jogamp.opengl.util.glsl.fixedfunc.impl -> jogamp.opengl.util.glsl.fixedfunc
- com.jogamp.nativewindow.impl               -> jogamp.nativewindow
- com.jogamp.newt.impl                       -> jogamp.newt

This sorts implementation details from the top level, ie skipping the public 'com',
allowing a better seperation of public classes and implementation details
and also reduces strings.

This approach of public/private seperation is also used in the OpenJDK.
