[WebProtegoAllowlistBypass] Add more histograms for debugging url checks

This CL adds these histograms

* SafeBrowsing.RT.LocalMatch.Result.(MainFrame|NonMainFrame).(Consumer|Enterprise|None)
This metric will help us understand how many allowlist checks are
happening for enterprise and for consumer real time URL checks.

* SafeBrowsing.BrowserThrottle.TotalDelay2.(ConsumerFullURLLookup|EnterpriseFullURLLookup|HashBasedCheck)
* SafeBrowsing.BrowserThrottle.TotalDelay2.EnterpriseFullURLLookup.(AllowlistChecked|AllowlistBypassed)
This metric will help us understand the impact on page load time when allowlist is
checked and when it is skipped

* SafeBrowsing.RT.ConsumerVersionReason
This metric will help us understand why the consumer version of the
real time URL check is chosen

Low-Coverage-Reason: Difficult to cover mojo impl.

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.
