pgstat: add pgstat_copy_relation_stats().

Until now index_concurrently_swap() directly modified pgstat internal
datastructures. That will break with the introduction of shared memory
statistics and seems off architecturally.

This is done separately from the - quite large - shared memory statistics
patch to make review easier.
