Add default parameter supplier conversor for function tests (#109969)

Continuation of
#109207 (review)

- Added a new function with the function test default generators (+ that PR BytesRef modifier)
- Applied it in all _trivial_ places. That is, where those same functions were being used

The idea here is to be able to easily add extra "test generators"
without having to touch everything.

As a next step, we could try to apply them to the remaining functions,
and for cases where some testcases don't make sense, add some kind of
"disableModifiers={a, b}" parameter. This way, we would declare
exclusions instead of inclusions, which is safer.
