macOS-12 CI/CD failure fix, periodic CMake regenerate

[bscottm]

• zlib now needs to be an explicit HomeBrew dependency. Previously, Apple distributed zlib as part of macOS. That is no longer the case.

• CMake: Periodic generate.py to update simulator CMakeLists.txt build files.

• PDP-10: Not entirely clear to me how/when AIO_CCFLAGS went missing (which causes generate.py to add USES_AIO to the CMake add_simulator arguments. Without AIO, the PDP-10 simulator users get a warning message with respect to AIO and networking.

@bscottm Nice way to slip in your previously discussed and still open cross thread interference changes. See discussion details in that original PR.

Well, I got a email with these contents:

@bscottm pushed 3 commits. • dfb6194 MAKEFILE: Add zlib to macOS deps • 6aa60d8 CMAKE: Regenerate, PDP10 needs USES_AIO • 0998e63 SCP: Fix scp_asynch_check cross-thread interference — View it on GitHub or unsubscribe. You are receiving this because you are subscribed to this thread.

I opened a browser to github.com/open-simh/simh and selected this PR in the Pull Requests and composed my comment.

Ahh, I now see that the subject on the above message was actually due to you had pushing the changes in this PR to your prior PR. Sorry for any confusion.

I'm not sure you should be mixing commits between different PRs though...

@markpizz: There are only two commits here, both related to the build system (makefile and CMake). There's nothing from my scp-async-check branch. You may have seen activity on my other branches when I updated my repo to sync with open-simh/master on several branches.

Nice work.
