Introduce `import.meta.primordials` for builtin JS

the `import.meta` object in Bun now has a `primordials` object which makes a handful of globals safe for access. Inside of bun: or node: modules, it is a special object (ownKeys is not implemented, so Object.keys() wont work on it)

- Array
- String
- `isPromise`
- `isCallable`
- `isConstructable`
- `tryGetById(foo, "bar')` which is like foo?.bar
- `arrayPush` which is like `Array.prototype.push`
- `Bun`
- `isAbortSignal`
