[subresource_filter] Add UMA for first check in a process This change adds a metric measuring how much wall time is spent evaluating a subresource load in the subresource_filter, for the first evaluation in a process. The reason this metric is interesting is that the subresource filter's ruleset is backed by a memory mapped file, so the first time we access it we may spend a disproportionate time blocking.

ChromiumChromium 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.

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.
