Improve Code Structure Based on New SwiftLint Ruleset

:recycle: Current situation & Problem

I have reworked the SwiftLint ruleset for the SPM version of CardinalKit to include rules added in the latest releases and restructured the file. This PR applies the new ruleset to the ResearchKitOnFHIR project.

:bulb: Proposed solution

Adds the new SwiftLint rules file and fixes any SwiftLint errors.
