Camera2: Add jpeg encoding support for all camera extensions

Enable consistent Jpeg output support for all present camera
extensions. Extensions with exclusive YUV_420 support will
include an extra SW encoding pass before the processed results
can be queued back to the client surface.

Bug: 179818844
Test: Camera CTS
