Alex Chi Z. 538ea03f73 feat(pageserver): allow read path debug in getpagelsn API (#10748) ...

## Problem

The usual workflow for me to debug read path errors in staging is:
download the tenant to my laptop, import, and then run some read tests.

With this patch, we can do this directly over staging pageservers.

## Summary of changes

* Add a new `touchpagelsn` API that does a page read but does not return
page info back.
* Allow read from latest record LSN from get/touchpagelsn
* Add read_debug config in the context.
* The read path will read the context config to decide whether to enable
read path tracing or not.
