Martin Robinson e81951a973 layout: Remove the obsolete layout tracing functionality (#35001) ... There were two kinds of layout tracing controlled by the same debugging option: - modern layout: Functionality that dumped a JSON serialization of the layout tree before and after layout. - legacy layout: A scope based tracing that reported the process of layout in a structured way. I don't think anyone working on layout is using either of these two features. For modern layout requiring data structure to implement `serde` serialization is incredibly inconvenient and also generates a lot of extra code. We also have a more modern tracing functionality based on perfetto that we have started to use for layout and IMO it's actually being used and more robust.
