ci : move [no release] check to dedicated check_release job (#23734)

* ci : move [no release] check to dedicated check_release job

Move the workflow-level \`if\` condition that skips builds when the commit
message contains \`[no release]\` into a lightweight \`check_release\` job.
All build jobs now depend on it via \`needs\` and check its output.

This ensures the skip logic is evaluated at the job level rather than at
the workflow level, which is the recommended approach for conditional jobs.

* cont : use `fast` runner
