Erik Grinaker 05d17a10ae rfc: add CPU and heap profiling RFC (#10085) ...

This document proposes a standard cross-team pattern for CPU and memory
profiling across applications and languages, using the
[pprof](https://github.com/google/pprof) profile format.

It enables both ad hoc profiles via HTTP endpoints, and continuous
profiling across the fleet via [Grafana Cloud
Profiles](https://grafana.com/docs/grafana-cloud/monitor-applications/profiles/).
Continuous profiling incurs an overhead of about 0.1% CPU usage and 3%
slower heap allocations.
