Track cmdlet parameter attributes in UseCompatibleCommands, check ValidateSet and enum parameters

Profiles in the compatibility rules currently do not track the attributes on parameters.

If they did this, it could statically check for things like

• ValidateSet parameters
• Enum-typed parameters (this is already possible to some extent)
• Mandatory parameters
• NotNull parameters

To do this, profiles should record attributes on each parameter. In the case of something like ValidateSet, it should track all the listed possible values for static checking later.

首先找出 UseCompatibleCommands 使用的相容性設定檔，以及目前如何記錄參數資訊。確定應如何表示 ValidateSet 值、列舉型別、必要參數和 NotNull 屬性，然後定義會使用這些中繼資料的靜態檢查。
