Add a user counter kCSSEnvironmentVariable_SafeAreaInsetBottom_FastPath

A new user counter kCSSEnvironmentVariable_SafeAreaInsetBottom_FastPath
is added to help us understand how often
style="bottom: env(safe-area-inset-bottom)" (also with calc()) is
used out of "env(safe-area-inset-bottom)".
That is kCSSEnvironmentVariable_SafeAreaInsetBottom_FastPath vs
kCSSEnvironmentVariable_SafeAreaInsetBottom.

For the case of "bottom: env(safe-area-inset-bottom)" where
IsBottomRelativeToSafeAreaInset() is set, we have a fast path to
handle it in CC. We would like to know what percentage of
env(safe-area-inset-bottom) goes to the fast path and what
percentage goes to the slow path.

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.
