Please describe the bug

Let's say we have an iceberg table like this,

CREATE TABLE
  db_1.tbl_1 (
    col_1 string,
    col_2 string,
    col_3 string
  )

If we have a query in trino,
SELECT col_1 FROM db_1.tbl_1 WHERE col_2 = 'my data'

The current schema projection for this query will include all of columns (col_1, col_2, col_3) regardless of the exact projection and filtering in the query.

The expected result of schema projection based on the query above should be col_1, col_2

How to reproduce:

Write a simple query in TestIcebergSplitSource.java

@Test
    public void testMyQuery()
    {
        assertUpdate("CREATE TABLE employees (id BIGINT, name VARCHAR, contacts ARRAY(ROW(email VARCHAR, phone VARCHAR, city VARCHAR)), dt VARCHAR) WITH (partitioning = ARRAY['dt'])");
        assertThat(computeActual("SELECT contacts[1].email FROM employees where dt = '123'").getRowCount()).isEqualTo(2);
    }

Check how table is scanned in getNextBatch in IcebergSplitSource.java
