Fix SPM build issues and add CI for future regression testing

@sampajano Would appreciate your team's review, merge, and 1.49.2 tag to fix the SPM build issues. And also to carry the fixes and CI forward to future releases.

@paulb777 Thanks for filing the issue!

I suppose this was the same one we've been discussion? i.e. regarding use_frameworks?

[paulb777]

@sampajano No, this is different. use_frameworks! is a CocoaPods issue. This PR fixes the Swift Package Manager build and adds CI to help keep it working.

[sampajano]

@paulb777 Oh! Sorry i didn't look closely!

Thanks so much for adding the CI for us!!

This looks great!

@HannahShiSFB PTAL too!

[sampajano]

Thanks so much for the new CI!

@HannahShiSFB PTAL — i suppose this fills in some holes which we have today. If we have more similar holes (i.e. build tests), we should fill them too. Thanks!
