vbo: Remove vbo_indirect_draw_func.

Remove the vbo_indirect_draw_func vbo callback and make the default
implementation use the drivers main draw callback function directly.
This will be needed with the next changes when drivers without own main
drivers DrawIndirect implementation get moved to the main drivers
Draw method.
