Missing CA1416 when type has SupportedOSPlatform and member has both SupportedOSPlatform and UnsupportedOSPlatform

Code:

```cs
using System.Runtime.Versioning;

public class C {
[SupportedOSPlatform ("macos12.0")]
public void M ()
{
Console.WriteLine (E1.A); // no warning
Console.WriteLine (E1.B); // no warning
Console.WriteLine (E1.C); // warning

Console.WriteLine (E2.A); // warning
Console.WriteLine (E2.B); // warning
Console.WriteLine (E2.C); // warning
}
}

[SupportedOSPlatform ("macos")]
public enum E1 : ulong {
[SupportedOSPlatform ("macos")]
[UnsupportedOSPlatform ("macos11.0", "Use 'Z' instead.")]
A,

[SupportedOSPlatform ("macos10.0")]
[UnsupportedOSPlatform ("macos11.0", "Use 'Z' instead.")]
B,

[UnsupportedOSPlatform ("macos11.0", "Use 'Z' instead.")]
C,

Z,
}

// No SupportedOSPlatform on the enum
public enum E2 : ulong {
[SupportedOSPlatform ("macos")]
[UnsupportedOSPlatform ("macos11.0", "Use 'Z' instead.")]
A,

[SupportedOSPlatform ("macos10.0")]
[UnsupportedOSPlatform ("macos11.0", "Use 'Z' instead.")]
B,

[UnsupportedOSPlatform ("macos11.0", "Use 'Z' instead.")]
C,

Z,
}
```

Build output:

```
Class1.cs(11,28): warning CA1416: This call site is reachable on: 'macOS/OSX' 12.0 and later. 'E2.A' is unsupported on: 'macOS/OSX' 11.0 and later (Use 'Z' instead.).
Class1.cs(13,28): warning CA1416: This call site is reachable on: 'macOS/OSX' 12.0 and later. 'E2.C' is unsupported on: 'macOS/OSX' 11.0 and later (Use 'Z' instead.).
Class1.cs(9,28): warning CA1416: This call site is reachable on: 'macOS/OSX' 12.0 and later. 'E1.C' is unsupported on: 'macOS/OSX' 11.0 and later (Use 'Z' instead.).
Class1.cs(12,28): warning CA1416: This call site is reachable on: 'macOS/OSX' 12.0 and later. 'E2.B' is unsupported on: 'macOS/OSX' 11.0 and later (Use 'Z' instead.).
```

I would expect E1.A and E1.B to raise warnings just like E2.A and E2.B does.
