Fix build worker callback arg missing correct page path

[huozhi]

What

The arg in the worker callback is alwasy any, when we access the page path the argument could be in different form as the arg types are different.

This PR align the argument type to object for isPageStatic, getDefinedNamedExports, hasCustomGetInitialProps methods in static worker. So they can share the similar shape of type of argument when accessing page path. This will avoid the case that logged page in the warning is undefined

Import the helpers from utils instead of workers as the worker itself don't need to contain other exports that is not used for static worker.

Why

This PR align the callback type of callback argument type of static worker, so that we could get the actual page path value in a type-safe way. We have 4 methods for static worker, exportPage, isPageStatic, getDefinedNamedExports, hasCustomGetInitialProps, which the rest of 3 methods share the same format of warnings but their argument are different. It's easily ended up with wrong argument type, and log with a bad page path in the warning.

Closes NEXT-2289

Sounds good, we can improve the types in a follow up PR 👍

I just want to make sure the types are correct so the next person doesn't create a new bug 😅
