Default @refresh pragma

[edemaine]

Could we add an option (here and the solid-vite-plugin that includes this) to specify the default @refresh pragma, for files that don't override @refresh? And I guess we'd need to give a name to the current default behavior, so you could opt back into it. Maybe /* @refresh replace */?

Motivation: The more I experience HMR (e.g. changing solid-playground), the more I find it buggy for the types of changes I make; for certain types of testing/debugging, I really want the full page reload every time. I basically don't trust the HMR results and manually reload every time. So I'd like to be able to specify a default of /* @refresh reload */.
