Register PgSQL FFTO tests in Makefile and groups.json (#5517)

Add Makefile rules for the two pg_lite_client-based tests:
  - test_ffto_pgsql_pipeline-t (links pg_lite_client.cpp)
  - test_ffto_pgsql_stmt_portal-t (links pg_lite_client.cpp)

The other 5 PgSQL FFTO tests use the default wildcard rule
(%-t: %-t.cpp) and don't need explicit Makefile entries.

Register all 7 new PgSQL FFTO tests in groups.json under
legacy-g4 and mysql84-g4 (same groups as test_ffto_pgsql-t):
  - test_ffto_pgsql_command_types-t
  - test_ffto_pgsql_concurrent-t
  - test_ffto_pgsql_errors-t
  - test_ffto_pgsql_large_resultsets-t
  - test_ffto_pgsql_mixed_protocol-t
  - test_ffto_pgsql_pipeline-t
  - test_ffto_pgsql_stmt_portal-t
