  [SourceManager] Expose max usage of source location space as a Statistic (#96292)

We have been running into source location exhaustion recently and want
to use the statistics to monitor the usage in various files to be able
to anticipate where the next problem will happen.

I picked `Statistic` because it can be written into a structured JSON
file and is easier to consume by further automation.

This commit does not change any existing per-source-manager metrics
exposed via `SourceManager::PrintStats()`. This does create some
redundancy, but I also expect to be non-controversial because it aligns
with the intended use of `Statistic`.
