Mms: Take into account image rotation.

Care was taken to not introduce additional jpeg-bitmap-jpeg conversions.

- Modify UriImage to track orientation via exif
- UriImage returns properly oriented bitmap via getResizedImageAsPart
(called from sendMmsWorker->resizeMedia)
- ThumbnailManager returns properly oriented bitmap via getBitmap
- attachment_view.xml: height: wraps around content
