Cannot Trace Invalid viz::LocalSurfaceIds

We do not want to generated Tracing Hash values for invalid viz::LocalSurfaceIds. As they will never be embedded anyways.

Unfortunately due to unit testing, and long standing disconnect in Renderer and Browser startup (https://crbug.com/419087), there are several paths that can lead to us attempting to trace these.

This change prevents the attempting to trace in these conditions, so that we don't crash tracing. Addressing the various root causes would be a significant overhaul and something to consider for the future.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
