feat(bundle): move bundled shared libraries to Contents/Frameworks

The Frameworks folder is the recommended location to store shared
libraries within macOS application bundles. Previously we stored them in
Contents/MacOS/lib.

Latest nightly builds already store all *.eln files under the Frameworks
folder, so it seemed like a good time to make the change with the
library bundler/embedder too.
