SCI32: Move priority comparison of ScreenItems into its own function
Rendering bugs in ScummVM are often caused by buggy game scripts relying on the last ditch sort, which is not the same in ScummVM as in SSCI (since the SSCI last ditch sort relies on a different memory architecture and is super buggy). However, these bugs do not show up very frequently these days, so it is easy to forget all the places that need to be checked when debugging a rendering problem that appears to be caused by sorting failure. This commit breaks out the last ditch comparison formerly in Plane::calcLists to hopefully make it more visible to future programmers. Refs Trac#9957.
