Auto merge of #75655 - nielx:fix/haiku-llvm-libz, r=Mark-Simulacrum

Disable zlib in LLVM on Haiku

PR #72696 enabled the option LLVM_ENABLE_ZLIB for the LLVM builds. Like NetBSD and aarch64-apple-darwin (see PR #75500), the LLVM build system not explicitly linking to libz on these platforms cause issues. For Haiku, this meant the runtime loader complaining about undefined symbols..
