Delete Ansible from installation process (#1604)

Resolves #1598
Resolves #1596

This reimplements the `load-tc358743-edid` service without Ansible,
which completes our process of eliminating Ansible from TinyPilot's
install process.

The last real piece was moving the installation of the
`load-tc358743-edid` from Ansible to Debian. The rest is just deleting
remaining Ansible files and stray references to Ansible.

Note that in deleting the Ansible environment setup, we delete `apt-get
update --allow-releaseinfo-change-suite` which we added in
#764. I don't think we
need this command anymore, but we can bring it back in the future if we
find that we need it.

## Manual tests

I ran the following manual tests:

* Verified keyboard and mouse still worked
* Verified that I could still adjust video settings
* Verified that audio still worked in H.264 (on Voyager systems)

For the following scenarios:

- [x] Install on a bare Raspbian system
- [x] Install on a bare Raspbian system with TC358743 enabled
- [x] Install a Pro Voyager image
- [x] Install a Pro Hobbyist image
- [x] Install a bundle on a Pro 2.6.0 Voyager image to simulate an
update

## Peer testing

To test this bundle run:

```bash
curl \
  --silent \
  --show-error \
  --location \
  https://raw.githubusercontent.com/tiny-pilot/tinypilot/master/scripts/install-bundle | \
  sudo bash -s -- \

  sudo reboot
```
