git_extensions: refactor and delete redundant functions

Merge pull request #9431 from RandomDSdevel/restore-semantically-significant-indentation-lost-accidentally-in-PR-9398

[Library/Homebrew/cli/named_args.rb] `to_formulae_to_casks()`:  Reasssociate its `rescue` Block with the Correct Enclosing Scope

`rescue` block with the right enclosing scope.

     PR #9398 accidentally removed some semantically significant indentation in
this function, thus inadvertently kicking the `rescue` block inside out to func-
tion scope, when it moved its code further up in the file.  This may well not
confuse a Ruby interpreter, but it could trip human readers up.  Compensate and
correct the overlooked offending oversight and potential refactoring mistake by
restoring only that indentation, leaving the function in its new location.

Refs #9398.

Add CPU family for M1, remove Intel Arrandale

According to reports, XNU’s CPU family identifier previously used for
the Westmere family (which Homebrew mislabels as the Arrandale family)
is now being reused for one of Apple’s M1 SoC models.

Resolve the conflict by splitting the list of CPU families and adding a
microarchitecture check.
