Preserve RemoteAuthenticationContext during JS interop

[halter73]

Preserve RemoteAuthenticationContext from Microsoft.AspNetCore.Components.WebAssembly.Authentication during JS interop in order to avoid errors during sign in and sign out like "There was an error trying to log you in: '"undefined" is not valid JSON'".

This didn't produce trim warnings because JSRuntime suppresses them. #39839 tracks adding trim-safe JSRuntime APIs.

I tried the suggested fix in #53819, but that did not fix the issue because type-level [DynamicallyAccessedMembers] only helps if something calls RemoteAuthenticationContext.GetType(). It does not mean if any part of the type is preserved, preserve all parts of the type. You can look dotnet/linker#1196, dotnet/runtime#49465, and dotnet/linker#1929 for the original motivation and test cases that were added when [DynamicallyAccessedMembers] was first allowed to target classes. The reason that it appeared to work with the DemoRemoteAuthenticationContextWithAttribute test case is because Blazor does not trim application assemblies by default. If you trim the application assembly, you will see the same issue.

Fixes #49956
Fixes #52291
Fixes #52619

Fixes #53409
