evas sw render: cutout rects may be used in multiple threads

several draw funcs keep a static Cutout_Rect *rects = NULL; variable
to cache cutout rects to avoid re-allocating them a lot etc. this is
fast and handy but we may use these from multiple threads. thats bad
.... mmmkay. so this fixes it the dirty way - makes them thread local.
:)

this fixes T3348 - the crash mentioned by @zmike

@fix
