Add modifications for ARM 64 ci
Needed to add a `release_linux_base` so arm could inherit from it.  Everything i believe is the same as x86 cpu except the crosstool which bazel did not like being defined twice.  @angerson do you think we should put this one in official for now or over in devinfra?  I'd say to put it in Official with a WIP tag somewhere.
Begin to add required changes to bazelrc and envs to support ARM64 in the new script system.
