Optimized DebloatAll and slimmed code more

added ' -and $_.NonRemovable -eq "False"' to the Get-AppxPackage code lines to help sort through apps that can't get deleted and just get skipped anyways.

Onedrive fixes and code reuse from GUI moved over to interactive script code.

Removed [CmdletBinding()] and Param() that wasn't being used.

Fixed Write-Output to Write-Host

Added ' -and $_.NonRemovable -eq "False"' to GUI code as well in the DebloatAll function
