Force disable spellcheck languages

Force-disables spellcheck languages. Unrecognized languages in that list will be ignored.

If you enable this policy, spellcheck will be disabled for the languages specified. The user can still enable or disable spellcheck for languages not in the list.

If you don't set this policy, or disable it, there is no change to the user's spellcheck preferences.

If the 'SpellcheckEnabled' (Enable spellcheck) policy is set to disabled, this policy has no effect.

If a language is included in both the 'SpellcheckLanguage' (Enable specific spellcheck languages) and the 'SpellcheckLanguageBlocklist' policy, the spellcheck language is enabled.
