Add Cookie.Count2 histogram with a higher max than Cookie.Count

According to current data (http://shortn/_7HvkBvMPRR) 1.3% of samples
have >4000 cookies, so end up in the "max" bucket of Cookie.Count. I
also have some experimental data that, on my laptop, >10,000
artificially-generated cookies contribute several seconds delay to
browser startup time.

This adds a new histogram with buckets for up to 100,000 cookies to help
estimate how common these very high cookie counts are in the wild and
deprecates the old Cookie.Count histogram.

It also updates histogram owners since battre@ is no longer working on
cookies.

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.
