The remaining codefactor issues are not related to this PR or I'm adopting the current conventions in the source code for consistency but breaks CodeFactor rules. |

…each screen full (PowerShell#8481) When using a screen reader or just getting the output of a table with lots of rows, the header is no longer on the screen and the columns may no longer make sense without the context. This change adds a `-RepeatHeader` switch to `Format-Table` to enable re-outputting the header after every screen full (minus 1 row). Expectation is that the user is piping the output to a pager (e.g. less) which uses the bottom row for pager information. I followed the `AutoSize` parameter as the way to get the parameter from the cmdlet into the deep formatting object where it's needed.
