Add the replication origin name and commit-LSN to logical replication worker errcontext

Hia,

We've added some information such as the command and the timestamp to
the error context message by commit abc0910e2. This patch adds further
information to it: replication origin name and commit-LSN.

This will be helpful for users to set the origin name and LSN to
pg_replication_origin_advance().

The errcontext message would become like follows:

*Before
ERROR: duplicate key value violates unique constraint "test_pkey"
DETAIL: Key (c)=(1) already exists.
CONTEXT: processing remote data during "INSERT" for replication
target relation "public.test" in transaction 726 at 2022-02-28
20:59:56.005909+09

* After
ERROR: duplicate key value violates unique constraint "test_pkey"
DETAIL: Key (c)=(1) already exists.
CONTEXT: processing remote data during "INSERT" for replication
target relation "public.test" in transaction 726 committed at LSN
0/14BFA88 and timestamp 2022-02-28 20:58:27.964238+09 from replication
origin "pg_16395"

I'm a bit concerned that the message may be too long.

I've attached two patches: the first one changes
apply_error_callback() so that it uses complete sentences with if-else
blocks in order to have a translation work, the second patch adds the
origin name and commit-LSN to the errcontext message.

Regards,
