Camera: Add support for multi-resolution input and output streams

- Multi-resolution output streams allow for variable output sizes for
logical multi-camera.
- Multi-resolution reprocessing allows for reprocessing of
variable size images.

Test: Camera CTS, VTS
Bug: 156254356
Change-Id: I4e8b14a4d6aabdb4b194483d93af53e033c08e28
