[Feature request] Swift Package Manager support

**What's your feature request? Please describe.**
Most of the current industry projects uses SPM for dependency manager, mlkit only allows cocopods.

**Mobile environment**
Android, IOS or both

iOS

**Additional context**

I have created temp project and resolved mlkit dependencies using pod, then created xcframework to directly use binary files in the project.

But there are numerous instances it would compile about symbols not found.
