feat: add world selection for multi-world WIT files

[jsturtevant]

Support WIT_WORLD_NAME env var in hyperlight-wasm-macro to select a specific world from WIT files containing multiple worlds.

@jprendes the build is failing on the sysprep root. I tried downgrading to cargo-hyperlight 0.1.6 and it didn't help. I Ideas what might be going on here? I don't see much in the error message that points me in the right direction.

error: failed to run custom build command for `hyperlight-wasm v0.12.0 (/mnt/vss/_work/hyperlight-wasm/hyperlight-wasm/src/hyperlight_wasm)`
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_RELEASE_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

[jprendes]

I changed src/hyperlight_wasm/build.rs lines 141-142

     cmd.status()
-        .unwrap_or_else(|e| panic!("could not run cargo build wasm_runtime: {}", e));
+        .unwrap_or_else(|e| panic!("could not run cargo build wasm_runtime: {:?}", e));

and now I got a more helpful error message

It looks like hyperlight-component-util changed in this PR, needs a newer version of indexmap, while wasmtime 36.0.5 doesn't.
