pageserver: use image consistent LSN for force image layer creation (#12547)

Browse Source 
This is a no-op for the neon deployment

* Introduce the concept image consistent lsn: of the largest LSN below
which all pages have been redone successfully
* Use the image consistent LSN for forced image layer creations
* Optionally expose the image consistent LSN via the timeline describe
HTTP endpoint
* Add a sharded timeline describe endpoint to storcon
