Aspnetcore: Protected browser storage

[danroth27]

Finish and ship https://docs.microsoft.com/aspnet/core/blazor/state-management#protected-browser-storage-experimental-package

A lot of the code exists here: https://github.com/aspnet/AspLabs/tree/master/src/ProtectedBrowserStorage/src

• [x] This feature relies on a server feature. This packaging requirement will likely requiring having to ship it separately from the other all-purpose Blazor component package.
• [x] Things to address: Add an optional scope to the Get \ Set \ Delete APIs that allows specifying additional scope for data protection
