Allow users to opt out of returning FPI data and block data from
pg_get_wal_block_info as an optimization. Testing has shown that this
can make function execution over twice as fast in some cases.
When pg_get_wal_block_info is called with "show_data := false", it
always returns NULL values for its block_data and block_fpi_data bytea
output parameters. Nothing else changes. In particular, the function
will still return the usual per-block summary of block data/FPI space
overhead. Use of "show_data := false" is therefore feasible with all
queries that don't specifically require these raw binary strings.
