GHOST: remove OpenGL depth buffer, remove code for other unused buffers

Browse Source 
Viewport drawing has moved to offscreen buffers, and we no longer need to have
depth, stencil, aa samples, sRGB buffers as part of the window. So all that
code is removed now. The depth buffer was the only one still being allocated,
its removal save a bit of memory.

Code by Germano and Brecht.
