Issue title: compile dothtml pages
 Issue body: Hello,
Is it possible to precompile dothtml and dotcontrol files in a similar way to using RazorGenerator in MVC projects?
I dont want to include these files in distribution package. In standard mvc app it was possible to compile it inside DLL file using RazorGenerator.

 Comment 0: Full precompilation is not currently supported.

You can however embed the pages into the resulting assembly as embedded resource, so you don't have to copy the Views folder. See https://www.dotvvm.com/docs/tutorials/control-development-markup-control-registration/2.0 - we have it documented for controls, but it works exactly the same for Views
 Comment 1: do you have plans to support precompilation?
 Comment 2: Yes, but the only thing we can promise that it's not going to happen very soon as it's not that easy and there is not that many benefits.
