fix: formatError() outside rollup context

[manucorporat]

Description

Fix formatError() to be able to compute the error frame outside the activeCtx (useful for SSR rendering if app crashes during execution).

Right now formatError() is not generating the frame automatically, even though throwing a error with all the necessary information.

When using Vite with dev SSR, custom user's code might run right after ssrLoadModule() and this code could crash, right now it's is missing nice printing, even though the source of the error is known!
