[rust] Update rust config to build backend for WASM

This change makes our rust toolchain support generating output for WASM:
1) Include the WebAssembly LLVM backend so we can generate WASM.
2) List wasm32-unknown-unknown as a target for rustc unconditionally,
which creates rust-std and supports compiling for that target.
