[Patch, Fortran, F03] PR 54147: Interface checks for PPCs & deferred TBPs

[Janus Weil]

Hi all,

here is a follow-up patch to my recent fix for PR 42418. Shortly after
committing it, I realized that the same checks should be done not only
for plain PROCEDURE declarations, but also for procedure-pointer
components and (deferred) type-bound procedures. So, what the attached
patch does, is to separate the checks out of their original place, put
them into a stand-alone routine and call this from different places in
order to apply the checks to the three cases mentioned above.

The new test cases are completely analogous to the one for 42418, but
tailored to PPCs & TBPs.

Patch was regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
