Bug Report: insert on duplicate key update missing BindVars

[wlx5575]

Overview of the Issue

In V18, the addition of trimming bound variables during insert needs to be included for each shard in this pull request: #14064. However, the scenario of 'insert on duplicate key' has been overlooked, and the bound variables added are not included for 'on duplicate key' variables.

Reproduction Steps

vschema
"t10": {
"column_vindexes": [
{
"column": "sharding_key",
"name": "hash"
}
}

create table t10
(
id bigint,
sharding_key bigint,
col1 varchar(50),
col2 int,
col3 int,
primary key (id)
) Engine = InnoDB;
