Standardize property attributes and refactor private properties.

This change:
*   Explicitly adds `nonatomic` to properties where thread safety is not required, improving performance.
*   Adds `atomic` to class properties and other properties where thread safety is important.
*   Refactors private properties in `ITRTestTraceRecorder` to be instance variables.
*   Simplifies the `EDODeviceDetector` by removing a redundant `started` property and using the channel's existence.
