ci: update x86 macOS to version 13 (#1474)

## Summary
macOS-12 has been deprecated by GHA and runners requesting those images
no longer run. As such, upgrade our macOS 12 runners to 13.

## Details
* Starting from macOS-13, binaries no longer have default 
`/usr/local/lib`  fallback search path. As such, the brew prefix now has
to be installed as  `DYLD_FALLBACK_LIBRARY_PATH`  for both ARM and x86
runners.

* There are compatibility issues with OpenSSL 3.4.0 installed within the
current macOS images, as such this PR pin version 3.0 instead.
