[roll] Roll fuchsia [feedback] Purge system log recorder memory

This is a modified reland of https://fxrev.dev/1248007. The
modifications allow us to easily unit test that purging memory doesn't
cause a crash.

System log recorder experiences high memory usage shortly after startup,
memory which is unlikely to be used again but is not reclaimed by scudo.
Experiments showed that explicitly purging memory after 150s yielded
significant improvements in memory usage that lasts well after the
purge.

Original-Fixed: 397695466
Tested: `ffx profile memory --process-names system_log_recorder --csv
--interval 1 > ~/feedback-memory-data`
Tested: `fx test //src/developer/forensics` with ASAN
