Add alias for debugging DomStorage batch tasks

This CL adds `base::debug::Alias` for `batch_task_count` and
`current_batch_size` within `RunBatchDatabaseTasks`.

The goal is to ensure these values are available in crash dumps to help
diagnose potential Out Of Memory errors (OOMs) related to large batch
sizes or task counts, by preventing the compiler from optimizing these
variables away.

This approach is used as an alternative to crash keys, regarding
potential thread-safety issues with setting crash keys from multiple
threads.

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.
