Remove profile tooling

Drop the profile Makefile target, the marina_profile test module,
the fprofx test dep and a stale README reference to a bench
target that no longer exists.

 The bundled `Dockerfile` produces the CI image (`lpgauth/erlang-scylla:28.3.1-6.2.3-amd64`) by layering OTP 28.3.1 (from the official `erlang` image) on top of `scylladb/scylla:6.2.3`. For local integration tests, run that image or a plain ScyllaDB container on `172.18.0.2:9042`.
