  Revert "[tsan] Use large address space mapping on Apple Silicon Macs"

This reverts commit bde2e5607167f3e9fd8c6b51275fc8ac654230a2.

This patch produces a compile failure on linux amd64 environments, when
running:

  ninja GotsanRuntimeCheck

I get various build errors:

  ../rtl/tsan_platform.h:608: error: use of undeclared identifier 'Mapping'
    return MappingImpl<Mapping, Type>();

Here's a buildbot with the same failure during stage "check-tsan in gcc
build", there are other unrelated failures in there.
