[new release] capnp (3.6.0)

CHANGES:

- Update README to talk about stdint, not uint (reported by @liyishuai).
  Also, remove out-of-date list of runtime packages needed. The build system can sort that out.

- Remove all `inlined` attributes (@talex5 capnproto/capnp-ocaml#87 capnproto/capnp-ocaml#88).
  These cause confusing compiler warnings for users, which can't be disabled automatically,
  and the inlining isn't being used anyway since capnproto/capnp-ocaml#83.

- Fix "Unknown interface" error (@talex5 capnproto/capnp-ocaml#85).
  It reported the UUID of the actual object, not the UUID that was requested.
  Also, add `Registry.pp_interface` for better error messages.

- Minor opam fixes (@talex5 capnproto/capnp-ocaml#84).
  Depend on dune >= 2.3 and don't try to build benchmarks; that only works on some platforms.

- Bump minimum OCaml version to 4.08.
  4.07 doesn't work due to janestreet/base#94.
