[cmake] Fix macOS frameworks, and icon set usage (#3782)

- The Xcode generator /mandates/ that you pass in the `.icon` directory
  into the build system, where it can then compose the asset itself.
- Assets.car and eden.icns were improperly handled; they are now
  automatically generated and should properly be applied as needed. I
  will need someone on Tahoe to confirm, however, as I am on Sequoia.
- Added some missing frameworks, ported from the KosmicKrisp branch.
