media/gpu: s/jpeg/mjpeg/ in mojo and the media/video interface

This CL follows up on the previous by changing the name of
the Mojo class and the media/video/jpeg_decode_accelerator
interface, so that:

Note that a Renderer/Video Capture client can perfectly use
a MjpegDecodeAccelerator to implement a JpegDecodeAccelerator,
since it'd be using a particular case of the former.

TBR=sadrul@ for services/ws/public/cpp/tests/
and for content/{browser,public} changes since
these are mechanical name substitutions.
