Update ScrollUpdateEventMetrics trace handling

We want to generate synthetic ScrollUpdateEventMetrics for an
experiment with ScrollPredictor. However these metrics were setup to
expect a valid `trace_id`. These are provided by `ui::LatencyInfo` when
input is received in the Browser process.

This change updates ScrollUpdateEventMetrics to make `trace_id`
optional. Which parallels most of the other metrics objects. We will
follow this up with `trace_id` generation later on in the
ScrollPredictor prototype.

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.

If you found a bug, please file it at https://crbug.com/new.
