Add patches for 3.7.14 needed for Apple Silicon

[samdoran]

Prerequisite

• Please consider implementing the feature as a hook script or plugin as a first step.
  • pyenv has some powerful support for plugins and hook scripts. Please refer to Authoring plugins for details and try to implement it as a plugin if possible.
• Please consider contributing the patch upstream to rbenv, since we have borrowed most of the code from that project.
  • We occasionally import the changes from rbenv. In general, you can expect changes made in rbenv will be imported to pyenv too, eventually.
  • Generally speaking, we prefer not to make changes in the core in order to keep compatibility with rbenv.
• My PR addresses the following pyenv issue (if any)
  • None

Description

Mostly the same patches from 3.7.13 are needed for 3.7.14 on Apple Silicon.

Tests

• My PR adds the following unit tests (if any)

Could you also port patches for the recently-added 3.8.14 and 3.9.14?

I'd be happy to, but I don't think those patches are needed for 3.8.14 and 3.9.14. I looked through the CPython source and the changes are already present in those versions and the need for a VARIADIC flag was solved in another way (based on reading the comments in the source).

Also, I've installed both 3.8.14 and 3.9.14 and ctypes compiled fine.

Thank you for merging!
