Revert StatisticsRecorder back to use a base::Lock.

This reverts the CL to use an absl R/W lock:
https://chromium-review.googlesource.com/c/chromium/src/+/3216667

As well as the follow up change on top of that:
https://chromium-review.googlesource.com/c/chromium/src/+/3378925

Reason for revert: We're seeing 10+ second hangs on iOS, unclear why,
appears to be starvation issues, despite that being unexpected. Needs
more investigation, reverting to fix the hangs to merge to iOS stable.

This CL bundles the changes together to revert.
