Fix lazy() with defaultProps (#14112)

* Resolve defaultProps for Lazy components

* Make test fail again

* Undo the partial fix

* Make test output more compact

* Add a separate failing test for sync mode

* Clean up tests

* Add another update to both tests

* Resolve props for commit phase lifecycles

* Resolve prevProps for begin phase lifecycles

* Resolve prevProps for pre-commit lifecycles

* Only resolve props if element type differs

* Fix Flow

* Don't set instance.props/state during commit phase

This is an optimization. I'm not sure it's entirely safe. It's probably worth running internal tests and see if we can ever trigger a case where they're different.

This can mess with resuming.

* Keep setting instance.props/state before unmounting

This reverts part of the previous commit. It broke a test that verifies we use current props in componentWillUnmount if the fiber unmounts due to an error.
