[STO] Consolidate reducers & action creators with RTK: experiemntalSettings

[MarioAslau]

What is this about?

As part of or ongoing effort to use Redux Toolkit to consolidate reducers and action creators we will continue using Redux Tool Kit to consolidate them into slices + remove the need for multiple files.

For this ticket, we'll focus on experimentalSettings actions and reducers into a slice file using RTK.

Acceptance Criteria

• These changes do not affect the UX of the app but will require a full e2e test to ensure flows are still working.
  • In addition to the pr_smoke_e2e_pipeline running, trigger the pr_regression_e2e_pipeline
  • Run the build_android_qa workflow so we trigger the app launch times tests as well.
• New slice is still able to consume and dispatch data using RTK slices
• Ensure that experimentalSettings data is still persisted
