Revert "Introduce support for hardware simulators, starting with ARM64"

This reverts commit c2e1a5edc438274159c6ef8e65455ac73723a8f1.

This breaks the build for x86_64 targets. This is because on target the libvixl is not included as a
library for the libart.so target build. The build of non-x86_64 targets only works because the
compilers removes the dead-code that contains the libvixl symbols.
