Dmitry Rodionov 44111e3ba3 Prohibit branch creation at lsn that was already garbage collected. ...

This introduces new timeline field latest_gc_cutoff. It is updated
before each gc iteration. New check is added to branch_timelines to
prevent branch creation with start point less than latest_gc_cutoff.
Also this adds a check to get_page_at_lsn which asserts that lsn at
which the page is requested was not garbage collected. This check
currently is triggered for readonly nodes which are pinned to specific
lsn and because they are not tracked in pageserver garbage collection
can remove data that still might be referenced. This is a bug and will
be fixed separately.
