Erik Grinaker a55853f67f utils: symbolize heap profiles (#10153) ...

## Problem

Jemalloc heap profiles aren't symbolized. This is inconvenient, and
doesn't work with Grafana Cloud Profiles.

Resolves #9964.

## Summary of changes

Symbolize the heap profiles in-process, and strip unnecessary cruft.

This uses about 100 MB additional memory to cache the DWARF information,
but I believe this is already the case with CPU profiles, which use the
same library for symbolization. With cached DWARF information, the
symbolization CPU overhead is negligible.

Example profiles:

*
[safekeeper.pb.gz](https://github.com/user-attachments/files/18141396/safekeeper.pb.gz)
