Auto-resize Predictor ListView when the height is too small

Prerequisites

• Write a descriptive title.

Description of the new feature/enhancement

When my shell windows are too small to display all ten predictions in ListView, it should reduce the size to be able to display a smaller number of predictions.

This is particularly applicable in CloudShell where the default window when you open CloudShell is too small for ListView and so fails silently when I try using F2 and gives this error message when I try to set:

PS /home/steven> Set-PSReadLineOption -PredictionViewStyle ListView
WARNING: The prediction 'ListView' is temporarily disabled because the current window size of the console is too small. To use the 'ListView', please make sure the 'WindowWidth' is not less than '54' and the 'WindowHeight' is not less than '15'.

Proposed technical implementation details (optional)

There are a few ways to improve this experience.

• Incorporate similiar error message that Set-PSReadLineOption gives when the user tries F2
• Make ListView number of results resizable based on the window.
• Make ListView number of results resizable based on the window and incorporate scrollable functionality to enable users to see the other results given a smaller window.

I improved the scrollable list view to be able to adjust the list height accordingly based on the terminal height, and print warning when the terminal size is too small to show the list view.
