[pgAdmin4][RM4037] COMMENTS from inherited fields are not present when seeing generated SQL from a table

Hi Hackers,

Attached is the patch which fixes the issue where comments added in child
table on inherited columns where not showing in reverse engineered SQL.

I have also made changes to show column details of inherited columns of
table, as well as for "of type" tables similar to pgAdmin3. eg-
CREATE TABLE public.inhactortest
(
-- Inherited from table public.actor: actor_id integer NOT NULL DEFAULT
nextval('actor_actor_id_seq'::regclass),
-- Inherited from table public.actor: first_name character varying(45)
COLLATE pg_catalog."default" NOT NULL,
-- Inherited from table public.actor: last_name character varying(45)
COLLATE pg_catalog."default" NOT NULL,
-- Inherited from table public.test_table: col1 integer,
-- Inherited from table public.test_table: col2 "char",
-- Inherited from table public.test_table: col3 character varying COLLATE
pg_catalog."default",
owncol integer
)
INHERITS (public.actor, public.test_table)
WITH (
OIDS = FALSE
)
TABLESPACE pg_default;

ALTER TABLE public.inhactortest
OWNER to postgres;

COMMENT ON COLUMN public.inhactortest.actor_id
IS 'in child c';
--

Kindly review.
