* Move integration types into code-server
This will be easier to maintain than to have it as a patch.
* Disable connection token
Using a flag means we will not need to patch it out. I think this is
new from 1.64?
* Add product.json to build process
This way we do not have to patch it.
* Ship with remote agent package.json
Instead of the root one. This contains fewer dependencies.
* Let Code handle errors
This way we will not have to patch Code to make this work and I think it
makes sense to let Code handle the request.
If we do want to handle errors we can do it cleanly by patching their
error handler to throw instead.
* Move manifest override into code-server
This way we will not have to patch it.
* Move to patches
- Switch submodule to track upstream
- Add quilt to the process
- Add patches
The node-* ignore was ignoring one of the diffs so I removed it. This
was added when we were curling Node as node-v{version}-darwin-x64 for
the macOS build but this no longer happens (we use the Node action to
install a specific version now so we just use the system-wide Node).
* Use pre-packaged Code
