Looks like this is from pulling in a new dep on //components:metrics in child processes. We'll need to avoid this, likely to introducing an abstraction layer so CallStackProfileBuilder doesn't directly depend on CallStackProfileMetricsProvider.

commit fd3a73980b82eea000403c2c9c1f204f6612e7cf

Rationalize call stacks targets in //components/metrics/BUILD.gn

Renames targets to better reflect what they provide. Removes the
:metrics dep from the target for child processes to avoid including
unnecessary browser-process-only code in those processes. Breaks the
direct dependency of CallStackProfileBuilder on :metrics by introducing
a receiver callback abstraction.
