  [bmalloc] Replace ssize_t with ptrdiff_t for portability.
https://bugs.webkit.org/show_bug.cgi?id=256010

Reviewed by Yusuke Suzuki.

This is the patch for Windows bmalloc implementation part 4 of N.

In Heap, ssize_t is used to pass +/- delta. Actually ssize_t is from posix and not portable.
Let's use ptrdiff_t instead for better portability.
