Feature: Improves Windows Update plugin

[LordHepipud]

Improves Invoke-IcingaCheckUpdates, splitting updates into different categories, allowing the check for the update count based on these categories Microsoft Defender, Security Updates, Rollup Updates and all Other Updates. The -UpdateFilter will only apply to the total update count, allowing additional customisation. By running the plugin with -Verbosity 1, it will now also print the list of the update names if the the thresholds are printing Warning, Critical or Unknown
