fix(packages/lazy-fn-vite-plugin): make dynamic function detection stricter

[marcalexiei]

Context & Description

Fix issue 2 reported in #216 (comment)

unknown file: Cannot read properties of undefined (reading 'name') This error appear when dynamic is the only function exported by the tuono library import { dynamic } from 'tuono'. We need to improve the internal vite plugin + adding this test case

---

To fix the issue I replaced all casting inside turnLazyIntoStatic with helper function from @babel/types that provide check the correct node runtime and provide types accordingly.
E.g.:

isCallExpression(node: Node | null | undefined, opts?: Opts<CallExpression> | null): node is CallExpression;

I also refactored types by giving them name to reference babel or vite to avoid any confusion.
