Add optional pid parameter to pg_replication_origin_session_setup().
Commit 216a784829c introduced parallel apply workers, allowing multiple
processes to share a replication origin. To support this,
replorigin_session_setup() was extended to accept a pid argument
identifying the process using the origin.
This commit exposes that capability through the SQL interface function
pg_replication_origin_session_setup() by adding an optional pid parameter.
This enables multiple processes to coordinate replication using the same
origin when using SQL-level replication functions.
This change allows the non-builtin logical replication solutions to
implement parallel apply for large transactions.
Additionally, an existing internal error was made user-facing, as it can
now be triggered via the exposed SQL API.
