This adds a property to select the maximum number of threads to use for conversion and scaling. During processing, each plane is split into an equal number of consecutive lines that are then processed by each thread. During tests, this gave up to 1.8x speedup with 2 threads and up to 3.2x speedup with 4 threads when converting e.g. 1080p to 4k in v210. https://bugzilla.gnome.org/show_bug.cgi?id=778974
