John Spray fb0e2acb2f pageserver: add page_trace API for debugging (#10293) ...

## Problem

When a pageserver is receiving high rates of requests, we don't have a
good way to efficiently discover what the client's access pattern is.

Closes: https://github.com/neondatabase/neon/issues/10275

## Summary of changes

- Add
`/v1/tenant/x/timeline/y/page_trace?size_limit_bytes=...&time_limit_secs=...`
API, which returns a binary buffer.
- Add `pagectl page-trace` tool to decode and analyze the output.
