Fix a few issues with the menu completion

[daxian-dbw]

PR Summary

This PR fixes 3 issues with the menu completion:

1. Fix menu completion to work with the predictive list view (fix PSReadLine 2.2.0 ListView affects the rendering of MenuComplete #1935 -- regression introduced in 2.2.0-beta1)
2. Fix menu completion to clear lines properly when the menu top changes on re-drawing (regression introduced in 2.2.0-beta1)
3. Fix how RightArrow, LeftArrow, UpArrow, and DownArrow navigate in the menu view (enhancement)

[NOTE] It's easier to review by ignoring the whitespace changes: https://github.com/PowerShell/PSReadLine/pull/1946/files?w=1 Most line changes are the new tests.

Navigation in menu view

Before the change, the RightArrow and LeftArrow don't work correctly:

After the change, RightArrow and LeftArrow work as expected and you can use either one of RightArrow, LeftArrow, UpArrow, and DownArrow to loop through the menu items.
