Subject: [PATCH] Update factory reset dialog to new UX spec

This is part of an upstreaming change for ag/18193725, which is being
split out because of its separate logic from the rest of the UX updates.
The commit message of that CL is copied below for reference.

- This change modifies the system progress spinner
(indeterminate/horizontal) for use on w3.

spec: https://docs.google.com/presentation/d/1YqqNzmgW6C6-zZJdhE3zTvxPe24BBn66FLYalpSgww0/edit#slide=id.gdea00a2fd1_0_169

Note that UI makes use of system color attributes:
- colorControlNormal (spinner)
- colorProgressBackgroundNormal (track)

Bug: 194441833
Bug: 192470870
Bug: 192470222

Test: manual check
      - Settings > System > Disconnect & Reset
      - Power > Shutdown
      - Power > Restart
