Fix: dotnet/aspnetcore-tooling#11197 automatic backing-field for @ref (dotnet/aspnetcore-tooling#707) 

This change makes @ref define a field for you by default. We didn't do
this originally because we weren't sure if the compiler generating a
field would always be what you want, and more importantly,
we didn't have the expressiveness to add an opt-out.

Now that we have directive attributes, it's easy to create an opt-out
for the field generation. The special thing about it is that where
you opt-out has to be static. For this reason the @bind:suppressField
attribute cannot be used with a value, you either have the flag or not.

Additionally, we don't support automatic field generation for
generics, because usually we can't write the field name. If we
want to in the future could make this work when the generic
type arguments are specified. So in the case of generics,
you have to opt-out, and you will get a diagnostic
that tells you so.\n\nCommit migrated from dadf9faf22
