Add 'make watch' (#12636)

* Add 'make watch'

This combines frontend and backend watch into a single command that runs
them in parallel on on SIGINT terminates both.

Termination is not super-clean but I guess it does not have to.

* move to tools/, trap more signals, remove gnu-specific flag

* simplify

## Building continuously
Both the `frontend` and `backend` targets can be ran continuously when source files change:
To run and continously rebuild when source files change:
````bash
# in your first terminal
make watch-backend
# in your second terminal
make watch-frontend
make watch
````
On macOS, watching all backend source files may hit the default open files limit which can be increased via `ulimit -n 12288` for the current shell or in your shell startup file for all future shells.
