Description of the new feature/enhancement

Expose the number of items shown in command completion list ListViewMaxHeight as a $PSReadLine variable to make it changeable from UI. This would probably also need to expose the (internal?) constant of HistoryMaxCount (10) as well, shown a few lines above.

Proposed technical implementation details (optional)

It would be useful to be able to freely change the number of items in the prediction list, is there any alternative while HistoryMaxCount is hardcoded?
