remove redundant _cogl_clip_stack_dirty() api

Browse Source 
The only place we were calling _cogl_clip_stack_dirty() was when
changing the current draw_buffer which also implies a change in
the current clip stack. _cogl_clip_stack_flush() would already
be able to quickly determine that the clip stack has changed by
checking ctx->current_clip_stack so there isn't really any need
to explicitly mark the clip_stack state as dirty.
