WebEventData.ParseEventArgsJson has invalid UnconditionalSuppressMessage for JsonSerializer.Deserialize

[eerhardt]

See the suppression here:

https://github.com/dotnet/aspnetcore/blob/1d04387cf3b68636f8ade0118334f87ae5f56f7d/src/Components/Web/src/WebEventData/WebEventData.cs#L61-L79

This suppression is not valid because there is no guarantee the eventArgsType hasn't been trimmed, and thus the Deserialization may fail, or behave differently, in a trimmed app.

We should remove this suppression and address the warning correctly so this code behaves the same with and without trimming. Potentially, we can use the same approach that we are taking with https://github.com/dotnet/aspnetcore/issues/45527.

This is the root cause of https://github.com/microsoft/fast-blazor/issues/280. In that issue, the Microsoft.Fast.Components.FluentUI.dll assembly is marked as IsTrimmable=true. The assembly contains some event arg classes, like MenuChangeEventArgs and DialogEventArgs. These classes are being trimmed, since their containing assembly is marked as IsTrimmable=true. However, when an app tries to use these events, it fails as described in the issue. This is because the constructors are being trimmed from the classes, causing the JsonSerializer.Deserialize call above to fail.
