Eliminate duplicated filter within (filter(TableScan)) plan

[Sevenannn]

Which issue does this PR close?

• TPCH Query 13 rewritten SQL contains duplicated filter expressions for all SQL based connectors / accelerators spiceai#3243

Rationale for this change

• This PR serves as an minor performance improvement for changes in Unparsing: fix joins unparsing when table scan contains filters #50 when rewriting plans that has aggregates with lhs / rhs with filter and scan containing same filter.

For query

        select
            c_custkey,
            count(o_orderkey)
        from
            customer left outer join orders on
                        c_custkey = o_custkey
                    and o_comment not like '%special%requests%'
        group by
            c_custkey

The rewritten query will be:
SELECT customer.c_custkey, count(orders.o_orderkey) FROM customer LEFT JOIN orders ON ((customer.c_custkey = orders.o_custkey) AND (orders.o_comment NOT LIKE '%special%requests%' AND orders.o_comment NOT LIKE '%special%requests%')) GROUP BY customer.c_custkey

Under the current approach, the filter orders.o_comment NOT LIKE Utf8("%special%requests%") will occur twice in final query, although this has no effect on query result correctness, it brings performance overhead by including duplicated conditions.

What changes are included in this PR?

• Use Hashset to accumulate filters instead of Vec in try_transform_to_simple_table_scan_with_filters to avoid adding duplicated filters
