http-utils: generate heap profiles with jemalloc_pprof (#11075)

Browse Source 
## Problem

The code to generate symbolized pprof heap profiles and flamegraph SVGs
has been upstreamed to the `jemalloc_pprof` crate:

* https://github.com/polarsignals/rust-jemalloc-pprof/pull/22
* https://github.com/polarsignals/rust-jemalloc-pprof/pull/23

## Summary of changes

Use `jemalloc_pprof` to generate symbolized pprof heap profiles and
flamegraph SVGs.

This reintroduces a bunch of internal jemalloc stack frames that we'd
previously strip, e.g. each stack now always ends with
`prof_backtrace_impl` (where jemalloc takes a stack trace for heap
profiling), but that seems ok.
