Refactor: rename function to evaluate a driver

No functional changes.

In #116823 the function `remap_driver_frame` was moved,
but the name doesn't exactly correspond to what the function is doing.

Since it evaluates the driver, with different parameters, it is now called
`evaluate_driver_from_rna_pointer`.

We could maybe remove the function because it is only called once.
