`windows-rdl` doesn't quite handle `...Gdiplus.Color`

[kennykerr]

This struct has a bunch of scoped constants that look like enum variants but are really const fields in metadata. We need to find a suitable way to represent those in RDL.

Ha, that's because it really was a nested enum inside the struct originally. 😭

class Color
{
public:
    
    enum
    {
        AliceBlue            = 0xFFF0F8FF,
        AntiqueWhite         = 0xFFFAEBD7,
        Aqua                 = 0xFF00FFFF,
        Aquamarine           = 0xFF7FFFD4,
.
.
.

protected:

    ARGB Argb;
};

This should probably just be a scoped enum in metadata... In RDL it might be:

#[repr(u32)]
enum Color {
    AliceBlue            = 0xFFF0F8FF,
    AntiqueWhite         = 0xFFFAEBD7,
    Aqua                 = 0xFF00FFFF,
    Aquamarine           = 0xFF7FFFD4,
.
.
.
}
