False positive CA2021 when calling Enumerable.Cast on types that have a primitive type conversion

### Describe the bug
I am getting false positives of rule CA2021 in my project on code that does work at runtime.

### To Reproduce
```csharp
uint[] a = [1, 2, 3];
var sequence = a.Cast();
```

Here the Cast triggers CA2021, even though generic `uint` can be casted to `int` no problem.

Runtime does fail for widening or narrowing conversions (int -> long, etc), so there the diagnostic is correct.
Just this specific path is a false positive.

### Exceptions (if any)
No exception
