can you please include executorch_backends and executorch_extensions in the install() call alongside executorch and executorch_core so that we don't have to coordinate with the EXPORT PR? that should be enough to get it to work no matter which one lands first

I've updated to install these targets. Because of the order of declarations in the file, I can't directly add to the existing executorch / executorch_core install, as it is above many of the backend declarations. To avoid causing a bunch of merge conflicts by rearranging it, I've added an install for these new targets alone. I can add the export directive once #8954 is merged.

if you change an example to use these targets, CI will prevent us from messing it up in the future and give this diff coverage

I've updated executor_runner to use the top-level backends and extensions targets. I'll update examples with the export changes, as well.
