[core] WeakEventManager+Subscription needs IEquatable (#13232)

Context: https://github.com/Vroomer/MAUI-master-detail-memory-leak Context: #12039 Using the Visual Studio's `.NET Object Allocation Tracking` profiler on the sample above I noticed after app launch: Microsoft.Maui.WeakEventManager+Subscription Allocations: 686,114 Bytes: 21,955,648 After spitting out my coffee, I drilled in a bit to see where these are being created: System.Collections.Generic.ObjectEqualityComparer<Microsoft.Maui.WeakEventManager+Subscription>.IndexOf It turns out this `struct` doesn't implement `IEquatable<T>`: https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1815 To solve this: * `Subscription` is private, so we can make it a `readonly struct`. * `dotnet_diagnostic.CA1815.severity = error` across the entire repo. * Implement `IEquatable<T>` for all `struct` types. After these changes, I can't find `Microsoft.Maui.WeakEventManager+Subscription` in the memory report at all. Which assuming means, I saved ~21 MB of allocations in this app. Note that this doesn't actually solve #12039, as I'm still investigating the leak. Maybe this partially closes the floodgate? * Fix `struct`s in Controls.Core Note that I did not update these, as they are some "internal" parts from Xamarin.Forms: * `Profile` * `Datum` We might actually just consider removing these in the future. * Suppress warnings in Compatibility I assume these structs aren't nearly as important, so ignoring a few. They appear to be called once at startup in most cases. * Disable `CA1815` in tests.
