stdio jsonrpc server npm package (#5332)

- [x] figgure out how to build the packages (that it installs native
optional package automatically)
- [X] Make the gluecode
- [x] expose both the lowerlevel api that desktop uses (~~send objects
and receive objects~~, getting path of rpc-server is enough)
  - [X] and the higher level api needed for bots (jsonrpc client)
  - [X] typescript types
- [x] automatically pick the right binary from npm or allow getting it
from env var, or give out an error (throw error)
- [x] find out how to dev locally (use local built core in dc desktop) -
there is the question of how to link the typescript client and the task
to add a search in the cargo target folder for a debug build or a
different way, find out some good flow that we can use and document for
dc desktop + locally built core development
- [x] build the packages in ci
- [x] fix that deltachat-rpc-server is not executable

postponed:
- [ ] publish from ci
   - [ ] add key/token to deploy to npm 

Closes #4694
