Allow to invoke a calculation belong to another models

[goldmedal]

Description

This PR allows the calculation to be used by another model through the relationship. Consider the case in wren-modeling-rs/wren-example/examples/calculation-invoke-calculation.rs:

.column(
    ColumnBuilder::new("customer_state_cf", "varchar")
        .calculated(true)
        .expression("orders.customer_state")
        .build(),
)

We can add a calculated field in order_items to access the calculated field customer_state in orders.

Known Issue

• Only allow one calculation in an expression currently. We will file another issue for it.
