## Bug
When trying to use app directory on Windows, the automatically created
`Layout.tsx` get's a lint problem for having a `<head>` element.
## Solution
Update the rule to check paths using `path.sep` rather than hardcoded
`/`
I also checked with `path.posix.sep` because some other rules was doing
that (both `path.sep` and `path.posix.sep`), so I'm just following
pattern
In #38647, @balazsorban44 has migrated the rule `no-img-element` to
typescript. The PR follows #38647 by migrating the entire
`eslint-plugin-next` to use typescript. Note it is still possible to
write new rules in javascript.
The PR does the following things:
- Migrates all `utils` to typescript
- All previous JSDoc are also converted to the type definitions
- Creates a utility method `defineRule`
- This is a stub function to provide the type check ability.
- With the `defineRule` we don't have to tediously import type
definition `Rule.RuleMetaData` and `Rule.RuleModule['create']` from
`eslint` anymore, `defineRule` will provide auto-complete and
typechecking for `meta` and `create`.
- Migrates all rules to typescript
- Extra type guards are also added to make typescript happy.
All existing `eslint-config-next` unit test cases passed after the
migration.

This lets us use modern JS/TS syntax in ESLint rules and avoid issues like #38530 and #36693

Fixes#33072
I documented all `esXXX` features to be sure that they were already polyfilled. Only `es2019` feature `Object.fromEntries` is not already polyfilled by nextjs.
I added some unwanted polyfill (that are polyfilled by nextjs).
I kept the `es5`, `es6` and `es2015` "as-is" as they contain functions that does not seem to be explicitly polyfilled (all `Math` functions or `Date.now` for example) in the [polyfill file](https://github.com/vercel/next.js/blob/master/packages/next-polyfill-nomodule/src/index.js)
