pgsql: Rename logical_replication_mode to debug_logical_replication_str

Rename logical_replication_mode to debug_logical_replication_streaming

The logical_replication_mode GUC is intended for testing and debugging
purposes, but its current name may be misleading and encourage users to make
unnecessary changes.

To avoid confusion, renaming the GUC to a less misleading name
debug_logical_replication_streaming that casual users are less likely to mistakenly
assume needs to be modified in a regular logical replication setup.
