  1. sys.FileStat.ctime updated with more accurate file creation time 

    Linux: Uses statx syscall on Linux to get stx_btime.tv_sec for this field only
macOS: Still uses the existing stat syscall, but accesses the macOS-only st_birthtime field instead

Historically, the POSIX standard did not require file systems to store the file creation time at all, so the stat syscall did not provide it. Modern file systems now store this value, and different operating systems provide it in different ways. The previous value of ctime from the stat syscall is actually the "status change time". This value may initially match the file creation time, but it can be updated after the file is modified in certain ways (including the file size changing, which is very common). The new value is more accurate, better matching how Haxe documents this field.
