View.Create, View.Build* and View.Update* should not be hidden from Intellisense

[TimLariviere]

The methods View.Create, View.Build* and View.Update* are currently generated with the attribute [<System.ComponentModel.EditorBrowsable(System.ComponentModel.EditorBrowsableState.Never)>].

This is good most of the time because this would otherwise pollutes Intellisense when writing views.

But when making custom controls, this makes them undiscoverable and we need to either guess the name of the functions or find them on Github. Either way this is bad.

I think one way to improve that would be to put them in their separate module?
That way when writing views, View.* wouldn't show build methods, and when making custom controls it would be shown to the developers.

Perhaps EditorBrowsableState.Advanced, though I'm not sure of its impact in the different toolchains (I don't think any F# tooling notices it).

Putting them in a different module is ok too, I think it is feasible (except perhaps for Create)
