PLAYRTS-5566 SwiftFormat and trim trailing whitespaces

[pyby]

Description

As a developer
I want to have same default Xcode configuration for all developers and better swift format
so that new PRs don’t have whitespace issues and different swift styles.

Important

For developers:

• Enable Xcode “While Editing: Including whitespace-only lines” option when this PR is merged.
• Run brew install swiftformat.

Testing manually the Xcode UI menu "Structure / Re-Indent", SwiftFormat tools has been tested, and it looks interesting to have it for a better swift code style.

Following #483, add swiftformat lint in build phases to help developers to check formatting during debug compilation.

Changes Made

• Add swiftformat in make check-quality and make fix-quality.
• Add swiftformat linter in build phases.
• Update all Swift files with swiftformat rules and Swift 5.10 updates.
• Improve few Swift codes to be conform to swiftformat rules.
• Update all Objective-C files with the Xcode menu "Structure / Re-Indent".

Checklist

• I have followed the project's style guidelines.
• I have performed a self-review of my own changes.
• I have made corresponding changes to the documentation.
• My changes do not generate new warnings.
• I have tested my changes and I am confident that it works as expected and doesn't introduce any known regressions.
• I have reviewed the contribution guidelines.
