[client] opengl: add splitmouse option

Browse source 
This feature was previously hardcoded enabled, it is now optional as
some hardware pipelines stall with the excessive flushes resulting in a
jumpy cursor. Default is disabled and may be re-enabled with
`-o opengl:splitmouse=1` or `-o opengl-basic:splitmouse=1` depending on
the renderer selected.
