[Blazor] InputSelect and related components analyzer

[javiercn]

For InputSelect, depending on the attributes used, the options provided in the body and the type used in the TValue, we might need to have specific <option value="">text</option>.

We should consider an analyzer that warns about incorrect usages. For example, nullable values likely require an empty options entry <option value="">text</option> and we likely need to treat "" as null in that scenario.
