Resolves: tdf#122301 ReferenceOrForceArray for FREQUENCY() parameters

It's yet unclear whether
ECMA-376-1:2016 OOXML 18.17.7.127 FREQUENCY
"A call to FREQUENCY shall be an array formula."
indicates that the entire formula expression should be in array
mode as well, see
https://bugs.documentfoundation.org/show_bug.cgi?id=122301#c8

If so, that will need a follow-up change.
