[NativeAOT] Preserve all constructors instead of no members (#18903)

`None` seems to be equivalent to not having the attribute at all. The type will be stripped by ILLink and ILC. The `PublicConstructors | NonPublicConstructors` seems to be a better option to keep the type while making it possible to trim as much of its members as possible.

This change resolves two warnings:
```
ILLink : warning IL2037: <Module>..cctor(): No members were resolved for 'None' on type 'Microsoft.Maui.Controls.Handlers.Compatibility.FrameRenderer.FrameView'.
ILC : warning IL2037: <Module>..cctor(): No members were resolved for '0' on type 'Microsoft.Maui.Controls.Handlers.Compatibility.FrameRenderer.FrameView'. 
```
(Note: these warnings will still be present for _static_ classes which don't have a static constructor)

@rolfbjarne I believe we don't need https://github.com/dotnet/runtime/pull/90154 anymore
