Convert "profile" image transforms to the new pathway

Summary:
Ref T7707. This ends up being sort of complicated: to support 100x100 images in T4406, we need to scale small images //up// so they look OK when we scale them back down with `background-size` in CSS.

The rest of it is mostly straightforward.

Test Plan:
  - Did an OAuth handshake and saw a scaled-up, scaled-down profile picture that looked correct.
  - Used Pholio, edited pholio, embedded pholio.
  - Uploaded a bunch of small/weird/big images and regenerated all their transforms.
  - Uploaded some text files into Pholio.
  - Grepped for removed methods, etc.
