Envoy v1.29.0 build fails on Mac OS

Title: Envoy v1.29.0 build fails on Mac OS

Description:
When I am building Envoy v1.29.0 on MacOS 12.7.1 with clang 14.0.0 I noticed an error

ec2-user@Mac-mini envoy-builds % gcc --version
Apple clang version 14.0.0 (clang-1400.0.29.202)
Target: x86_64-apple-darwin21.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Envoy build error

Undefined symbols for architecture x86_64:
  "cel::interop_internal::ProtoStructValueToMessageWrapper(cel::Value const&)", referenced from:
      cel::interop_internal::ToLegacyValue(google::protobuf::Arena*, cel::Handle<cel::Value> const&, bool) in libinterop.a(interop.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Target //contrib/exe:envoy-static failed to build
INFO: Elapsed time: 136.522s, Critical Path: 46.32s

I've tried both conrtib and not contrib build but I have the same issue.

Repro steps:

1. Use mac 12.7.1 or 11.7.10 (on aws ami-06bf601fad285cc69 or ami-0da052d2225304b8f)
2. Setup CI tools
3. run bazel build -c opt envoy
4. Notice error at the last step

I've noticed that more people have the same issue Homebrew/homebrew-core#160068

I think it was likely I was just the first to hit this. If this is WONTFIX, we should update documentation to say building on MacOS no longer possible after relevant commit. Wondering how many people are running MacOS instances in the cloud.

i think it should be resolvable one way or other

to clarify - macos does build, as we are building/testing in ci still (macos12 github runners)

i believe the constraint is to use the correct versions of compiler - it may be that our ci just builds less and excludes cel - not sure and no way to test

the setup for the macos12 images is here https://github.com/actions/runner-images/blob/main/images/macos/macos-12-Readme.md - i dont see any setup for this on our end (here https://github.com/envoyproxy/envoy/blob/main/ci/mac_ci_setup.sh) so assume that we are just using whatever is default in the macos12 image

update documentation to say building on MacOS no longer possible after relevant commit

perhaps we can (figure out and) specify what does work

git bisect says this is caused by bd1dca3

@phlax that's a fairly old version of macOS for CI. Is there a runner based on macOS version 14 we can use?

Thanks for the extra context; I hadn't seen that.
