Broken linkage seen in #232580

[carlocab]

Needs fixes to build. See #232571

[cho-m]

Skipping some tests on macOS which may just be flaky. Existing bottles are broken so I think we should just merge.

Can deal with 15-arm64 later. Failure will temporarily go away in Xcode 16.4 as Apple restored the deprecated behavior that LLVM removed. May fail again in Tahoe release.

[github-actions]

@carlocab has requested bottles to be published to this PR.

Caution

Please do not push to this PR branch before the bottle commits have been pushed, as this results in a state that is difficult to recover from. If you need to resolve a merge conflict, please use a merge commit. Do not force-push to this PR branch.

We may want to apply the patches at #232571 so that the headers here work on Xcode 16.3, at least?

I don't think it fixes LLVM 19+ error which looks due to usage of std::basic_string<uint8_t> at https://github.com/OpenLightingProject/ola/blob/master/include/ola/io/ByteString.h#L40

At least the char_trait failures are often due to not using a standard specialization https://en.cppreference.com/w/cpp/string/char_traits.html and relying on generic implementation (https://reviews.llvm.org/D157058)
