[Blazor] Restore client-side state after failing to reconnect to the circuit

[MackinnonBuck]

As part of the changes in #55723, Blazor Server apps will automatically reload the page during reconnection if the underlying circuit no longer exists. We should consider enhancing this experience further by automatically restoring client-side state.

This would likely include user input for the following HTML elements:

• <input>
• <select>
• <textarea>

However, this does not include restoring server-side state, as that is tracked by #30344

By the way this was done in my PR of #32122

It gave an opt-in possibility for clients to automatically reload the page once a rejected circuit was detected.

This is not something that we plan to do since the alternative solution is covered by the pause and resume feature already.
