MDEV-35948: Test OG replicate_*s with long lists

Assert that 1st-gen `replicate_*` filter variables display their input – including long but reasonable lists – correctly (without truncation) in * direct SELECT * [semi-new] INFORMATION_SCHEMA.GLOBAL_VARIABLES.VARIABLE_VALUE * [new] SHOW REPLICA STATUS This tests the fields affected by MDEV-35693 (an 11.6 oversignt). Also test the input `DEFAULT` as part of this edge-case testing.
