[Tooling] Refactor Fastlane lanes to use lanes and actions

[pylapp]

Description

Today, some tools are used for the proejct software quality: SwiftLint as sources linter, SwiftFormat as sources formatter, Periphery as dead code tracker.
These tools can be used in CLI mode.
For consistancy reasons beteen the package repository and the design system toolbox repository, and the ease implementation and maintanance of CI/CD workflows, Fastlane commands have been dedined in Fastfiles to just call the tools as CLI.

Issue

It could be nice to replace CLI commands for linter, formatter and dead code tracker witht he suitable Fastlane actions.
