Validates that child_spec options match the module's options_schema/0.
Behaviour conformance is enforced separately (and at hard-error severity)
by BB.Dsl.ValidateChildSpecBehavioursTransformer; this verifier assumes
every wired-in module is already a proper component and so always has
options_schema/0 defined.
Options containing param() references are skipped from validation as they
will be resolved at runtime.
