[IndexFilters] Remove IndexFiltersManager, reinstate useSetIndexFiltersMode (#10745)

### WHY are these changes introduced?

We recently removed the logic to disable page actions when in filtering
mode, so the work to extract the filtering state into global context is
no longer required, and should be cleaned up. This PR reverts things to
how they were before https://github.com/Shopify/polaris/pull/10490/files
merged.
