Reusable bundling/distribution for all platforms

[wravery]

We need a way to get/reuse a shared installation of the CEF binaries when installing a Tauri app. We could try to use the existing CEF_PATH mechanism, as long as we have instructions for how to create it more easily than asking the end-user to run export-cef-dir. It might be better to produce release artifacts and build an on-demand downloader/updater crate that we can invoke from the Tauri bundler/updater as needed.

I had hoped for chromiumembedded/cef#3836 to get reasonable close to something when we were to start looking into this so we could simply embed CEF for a few months to bridge the gap but seems like they need quite a bit more time. :/

(Really just wanted to link the upstream issue here)

Yeah, that's a big part of it, especially if we want to support multiple versions from a shared install. There are also some tweaks we'll need in this project to either make them compatible with other package layouts (e.g. on Nix), or to adapt those packages to match the shape we're using in the shared directory.
