adds conditional cmp removing use of libwebrtc on windows/freebsd

They cant compile livekit yet. This removes microphone and echo cancellation on those platforms however they can not join calls due to the same cause so it does not matter.

  - Example: avoid `let _ = client.request(...).await?;` - use `client.request(...).await?;` instead
 * When implementing async operations that may fail, ensure errors propagate to the UI layer so users get meaningful feedback.
 * Never create files with `mod.rs` paths - prefer `src/some_module.rs` instead of `src/some_module/mod.rs`.
+* When creating new crates, prefer specifying the library root path in `Cargo.toml` using `[lib] path = "...rs"` instead of the default `lib.rs`, to maintain consistent and descriptive naming (e.g., `gpui.rs` or `main.rs`).
+* Avoid creative additions unless explicitly requested
+* Use full words for variable names (no abbreviations like "q" for "queue")
+* Use variable shadowing to scope clones in async contexts for clarity, minimizing the lifetime of borrowed references.

+  ```rust
+  executor.spawn({

+      async move {
