Make blink::TransformationMatrix API similar to gfx::Transform, step 2

This is to prepare for the merge of TransformationMatrix and
gfx::Transform.

- Remove the self reference return value of mutation methods. The
  return value were mostly used in unit tests. Now let unit tests
  use test helpers. The return value might cause mistaken mutations
  when the developers think they were not mutation methods.

- Add static method MakeScale() and MakeTranslation() for faster
  construction of TransformationMatrix from 2d scale or
  translation.

- Rename ApplyPerspective() to ApplyPerspectiveDepth() which is the
  name used in gfx::Transform.

- Rename ScaleNonUniform() to Scale() which is the name used in
  gfx::Transform.
