Benjamin Williams ab009c27b4 Refactor WebRTC self assignments in if clauses
This change refactors existing self-assignments within if clauses across
the WebRTC codebase.

*Why:*

- Bug Prevention: Assignments within conditionals are frequently
  unintended errors, often mistaken for equality checks.

- Clearer Code: Separating assignments from conditionals improves code
  readability and reduces the risk of misinterpretation.
