turnip: Setup stream-output when linking program

turnip: Setup stream-output when linking program

Mostly taken from fd6_program.c.

v2. Note that it forces to use full VS instead of binning pass VS if
there's stream output as the binning pass VS will have outputs on
other than position/psize stripped out, which is the same as freedreno.

v3. fix indentation.

v4. Use register index instead of location when setup streamout.
