rust/wrapper.h: define memory_order enum
Add stub definition of memory_order enum in wrapper.h.
Creating Rust bindings from C code is done by passing the wrapper.h header to `bindgen`. This fails when library dependencies that use compiler headers are enabled, and the libclang that bindgen detects does not match the expected clang version. So far this has only been observed with the memory_order enum symbols from stdatomic.h. If we add the enum definition to wrapper.h ourselves, the error does not happen.
Before this commit, if the mismatch happened the following error could come up:
/usr/include/liburing/barrier.h:72:10: error: use of undeclared identifier 'memory_order_release' /usr/include/liburing/barrier.h:75:9: error: use of undeclared identifier 'memory_order_acquire' /usr/include/liburing/barrier.h:75:9: error: use of undeclared identifier 'memory_order_acquire' /usr/include/liburing/barrier.h:68:9: error: use of undeclared identifier 'memory_order_relaxed' /usr/include/liburing/barrier.h:65:17: error: use of undeclared identifier 'memory_order_relaxed' /usr/include/liburing/barrier.h:75:9: error: use of undeclared identifier 'memory_order_acquire' /usr/include/liburing/barrier.h:75:9: error: use of undeclared identifier 'memory_order_acquire' /usr/include/liburing/barrier.h:72:10: error: use of undeclared identifier 'memory_order_release' panicked at [..]/.cargo/registry/src/index.crates.io-6f17d22bba15001f/bindgen-cli-0.70.1/main.rs:45:36: Unable to generate bindings
To fix this (on my system) I would have to export CLANG_PATH and LIBCLANG_PATH:
export CLANG_PATH=/bin/clang-17 export LIBCLANG_PATH=/usr/lib/llvm-17/lib
With these changes applied, bindgen is successful with both the environment variables set and unset.
Since we're not using those symbols in the bindings (they are only used by dependencies) this does not affect the generated bindings in any way.

rust: add bindgen step as a meson dependency
Add bindings_rs target for generating rust bindings to target-independent qemu C APIs.
The bindings need be created before any rust crate that uses them is compiled.
The bindings.rs file will end up in BUILDDIR/bindings.rs and have the same name as a target:
ninja bindings.rs
