feat(protocol-designer): delete unused code

[jerader]

closes AUTH-645

Overview

We are free to merge this in since the PD release will be off of the release branch!

This PR deletes unused code and moves a few components into the correct folder (such as LabwareOnDeck, getUnusedEntities). There are also a few redux actions/selectors/reducers that were deleted because they are no longer in use. Those include:

1. thermocycler profile step -> the redesign has it contained in a modal and keeps track of stuff via local states
2. a bunch of hints -> we deprecated most of them for the redesign. only remaining hints are for exporting a protocol with unused hardware and changing your magnetic module version
3. redux actions related to navigation -> we use react-router-dom now for navigation
4. stuff related to expanding and collapsing steps and multi-steps -> we no longer allow expanding/collapsing steps at all

Additionally, all css style sheets are officially deleted 🗑️
