Bump LLVM version of the OSS build and remove reference to the `llvm_disable_optional_support_deps` OSS build https://buildkite.com/bazel/crubit/builds/918#01887140-6750-4181-bb70-ca4eb82c3f64 failed, most likely because lifetime_analysis uses a function that got introduced very recently. While bumping the LLVM version to `afb73f7a913ec8e7e8704afe18784571f320ebf6` and testing the change locally, the build failed due to missing `llvm_disable_optional_support_deps`, which [was recently removed](https://github.com/llvm/llvm-project/commit/7b5d6cd7fcac2b9e06338f2497fed9039360924a#diff-176ef3798608bb3fcb9a8a6341bbd6fd2eb2df52967d443dd2b0cb0a393a5681). Thus remove references to it in Crubit as well. Then I ran into `llvm-project/llvm/BUILD.bazel:184:11: no such package '@llvm_zlib//': The repository '@llvm_zlib' could not be resolved: Repository '@llvm_zlib' is not defined and referenced by '@llvm-project//llvm:Support'`, so add `llvm_zlib` to dependencies as well.

Crubit is an experimental bidirectional bindings generator for C++ and Rust.
Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.
Crubit allows for C++ code and Rust code to call each other without manually wrapping the APIs in an FFI-friendly interop layer. For example, a C++ function like this:
bool IsAbsPath(std::string_view path);
... becomes callable from Rust as if it were defined as:
pub fn IsAbsPath(path: std::string_view) -> bool {...}
Crubit automatically generates ABI-compatible bindings for structs (which can be passed both by value and by reference), functions, and methods, for a large variety of types. (Trivial types, nontrivial types, templated types, etc.)
