Add existing_initdb_timeline_id param to timeline creation (#5912)

Browse Source 
This PR adds an `existing_initdb_timeline_id` option to timeline
creation APIs, taking an optional timeline ID.

Follow-up of  #5390.

If the `existing_initdb_timeline_id` option is specified via the HTTP
API, the pageserver downloads the existing initdb archive from the given
timeline ID and extracts it, instead of running initdb itself.
