[BUG] exec attempts to validate env_file for a different non-dependent service

[ollie-bell]

Description

Given two services foo and bar where foo defines an env_file entry as a non-existent file. Running docker compose exec bar ... fails due to "env file not found".

This is inconsistent with e.g. docker compose up bar which runs successfully without attempting to validate the env_file of service foo

Steps To Reproduce

# compose.yaml
services:
  foo:
    image: hello-world
    env_file:
      - /does/not/exist/.env
  bar:
    image: hello-world

run:
docker compose exec bar bash

result:
env file /does/not/exist/.env not found: stat /does/not/exist/.env: no such file or directory

Compose Version

v5.0.2

This is a gap from #13156 where I fixed ps/logs/down but missed exec and some other commands. PR incoming.
