[flang] Omit parent components for references to bindings (#84836)

https://github.com/llvm/llvm-project/pull/78593 changed expression
semantics to always include the names of parent components that were
necessary to access an inherited component. This turns out to have
broken calls to inherited NOPASS procedure bindings. Update the patch to
omit explicit parent components when accessing bindings, while retaining
them for component accesses (including procedure components).
