Change macOS mmap tag to fix conflict with IOAccelerator 
Tag 100 is assigned to "IOAccelerator" (the GPU driver stack on Apple silicon), which makes for confusing output when debugging.

To avoid conflicts, use a tag in the reserved application-specific range from 240–255 (inclusive).

All assigned tags: 94d3b45284/osfmk/mach/vm_statistics.h (L773-L775)
