[compiler-rt][asan] use full vm range on apple silicon macs

We previously shrunk the mmap range size on ios, but those settings got inherited by apple silicon macs.
Don't shrink the vm range on apple silicon Mac since we have access to the full range.

Also don't shrink vm range for iOS simulators because they have the same range as the host OS, not the simulated OS.
