[blink] Add crash keys to investigate ScripedIdleTaskController OOM.

ScriptedIdleTaskController is a top source of OOM, spread across many
magic signatures (go/chrome-idle-tasks-oom-fdoray). However, it's not
clear if this is mostly caused by a large number of IdleTask objects, a
large number of scheduler idle tasks (there may be more scheduler idle
tasks than IdleTasks) or a problem in in the data structure used by the
scheduler to hold idle tasks. To get to the bottom of this, this CL
adds crash keys with:
- The maximum number of pending IdleTasks observed in a single
  ScriptedIdleTaskController.
- The maximum number of pending scheduler idle tasks observed from
  a single ScriptedIdleTaskController.

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.
