Format compiler sources with ocamlformat (rescript-lang#6901)

* add with-dev-setup group

* update dune-project and ocamlformat-ignore

* ci: remove --with-dev-setup

* ocaml 4.10

* delete all ocamlformat

* install ocamlformat

* increase cache version

* remove grep

* add with-test group

* restore cache version

* use v3 cache

* ocamlformat-ignore: add compiler/ext/js_reserved_map.ml

* chore: format
