ESQL: TO_LOWER process all values (#124676)

Make `TO_LOWER` and `TO_UPPER` process all values it received.

This is quite large because it borrows a lot of code from the regular
evaluator generator to generate conversions so we can use the Locale.
That change propagates to the order of some parameters and to the
`toString` and a few more places.

Closes #124002
