Adds better buildtool errors when using byond 514 or older (#81129)

Every time someone asks what -DCBT means i lose sleep so here's a
slightly invasive solution.
Build will now check if the dm version is at least 515.1597 (first
version with -D switch), at the cost of having to run dry dm.exe run.
