Flags enums should be sorted

[verdie-g]

I would like to suggest a new rule that, with an enum like that

[Flags]
public enum AttrCapabilities
{
    AllowView = 1 << 0,
    AllowCreate = 1 << 1,
    AllowChange = 1 << 2,
    AllowFilter = 1 << 4,
    AllowSort = 1 << 8,
}

would transform that code

class Person
{
    [Attr(Capabilities = AttrCapabilities.AllowChange | AttrCapabilities.AllowFilter | AttrCapabilities.AllowView)]
    public string? FirstName { get; set; }
}

to

class Person
{
    [Attr(Capabilities =  AttrCapabilities.AllowView | AttrCapabilities.AllowChange | AttrCapabilities.AllowFilter)]
    public string? FirstName { get; set; }
}

My use-case is that all properties of my domain objects are marked with these flags and it would help visually scanning them if they were sorted.

I believe this rule would be better implemented in a separate analyzer project.
