[PM-7846] Implement a rust based native messaging proxy and IPC system (#9894)

* [PM-7846] Implement a rust based native messaging proxy and IPC system

* Only build desktop_proxy

* Bundle the desktop_proxy file

* Make sys deps optional for the proxy

* Restore accidentally deleted after-sign

* Update native cache to contain dist folder

* Add some test logging

* Native module cache seems very aggressive

* Fix invalid directory

* Fix debug print

* Remove cache force

* Remove cache debug code

* Only log to file in debug builds

* Place the binary in the correct place for mac and make sure it's signed

* Fix platform paths

* Test unsigned appx

* Revert "Test unsigned appx"

This reverts commit e47535440a.

* Fix comment

* Remove logs

* Use debug builds in native code, and test private path on MacOS

* Add connected message

* Update IPC API comments

* Update linux to also use XDG_ dir

* Update main.rs comment

* Improve docs and split some tasks spawned into separate functions

* Update send docs and return number of elements sent

* Mark `listen` as async to ensure it runs in a tokio context, handle errors better

* Add log on client channel closed

* Move binary to MacOS folder, and sign it manually so it gets the correct entitlements

* Fix some review comments

* Run prettier

* Added missing zbus_polkit dep

* Extract magic number and increase it to match spec

* Comment fix

* Use Napi object, combine nativeBinding export, always log to file

* Missed one comment

* Remove unnecessary generics

* Correct comment

* Select only codesigning identities

* Filter certificates

* Also add local dev cert

* Remove log

* Fix package ID

* debug_assert won't run the pop() in release mode

* Better error messages

* Fix review comments

* Remove unnecessary comment

* Update napi generated TS file

* Temporary fix for DDG
