I would to run this on m1 mac, can we push arm64 image to docker hub?

For #1370 I plowed through some tweaks to build and test natively with an m3 macbook:

Here's the diff I worked with, probably needs cleaning up to minimize the delta.
This worked for me, except for

• passing the integration/python tests (didn't look into this)
• needed to exclude //test/adaptive_load/, failure:

Undefined symbols for architecture arm64:
  "protobuf::reflection::google_rpc_status::kFileDescriptorInfo", referenced from:
      protobuf::reflection::test_adaptive_load_fake_plugins_fake_metrics_plugin_fake_metrics_plugin::kDeps in fake_metrics_plugin_descriptor.pb.o
  "protobuf::reflection::envoy_config_core_v3_extension::kFileDescriptorInfo", referenced from:
      protobuf::reflection::test_adaptive_load_fake_plugins_fake_metrics_plugin_fake_metrics_plugin::kDeps in fake_metrics_plugin_descriptor.pb.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Command line that works:

bazel test //test/... -- -//test/adaptive_load/...
