* chore: pin caniuse-lite versions
Testcases in packages/babel-preset-env/test/fixtures/debug/browserslists-defaults-not-ie
depends on specific caniuse-lite versions. We pinned the version here
so we don't have to deal with fixture different in e2e-tests
where all deps will be updated and tested.

* Allow rest/spread on polyfilled or builtin iterables when `Symbol` unsupported
Currently, when `Symbol` is not supported, we allow using rest/spread with:
- arrays
- strings
- arguments
With this PR, it will be also possible to use it with
- maps
- sets
- binary arrays
While in old browsers es6 builtins would still need to be polyfilled, it's way
easier to polyfill them because `Symbol` cannot be reliably polyfilled.
I didn't use `instanceof` becase:
- it doesn't work with polyfills not attatched to the global scope
- when using Babel to load polyfills, it would force the inclusion of `Map` and `Set` polyfills even if they are not used
Downside: the current approach of relying on `toString || construcor.name` doesn't work with subclasses.
* Don't use Array.from for array-like objects
* Extract for-of iterator handling to a helper
Dis greatly recudes the code size when for-of is used multiple times across the
codebase. Also, makes it easier to read what's happening in a compiled loop.
* Unify spec and loose code
* Legacy implementation fallback
* Update tmp var name
* Updates from review and after rebase
