feat(mv3-part6): Opt into async handler for stores with async work

[sfoslund]

Details

Follow up to https://github.com/microsoft/accessibility-insights-web/pull/5877, which allowed us to opt stores into supporting async handlers. These changes to not touch any stores that do not have async work, since by default stores support sync handlers. The stores changed in this file correspond to actions that were converted to async in previous PRs.

Motivation

Feature work.

Context

These changes ensure that any async work in action handlers is properly awaited, which will protect from the manifest v3 service worker timing out when async work is still happening.
