Remove the gutenberg-block-directory experimental flag (#23389)

* Remove the gutenberg-block-directory experimental flag

This removes the flag and its UI, enabling the block directory by default.

Note that it does not change the API namespace, which is still `__experimental`.

* Remove the experiment toggle in block directory e2e.

* Move e2e tests into the editor folder and out of experiments.
