DownSample Upload image to be shown in UploadMediaDetailFragment to handle OOM, Bitmap Too large exception (#3830)

* Fixes #3829
* DownSample Upload image to be shown in UploadMediaDetailFragment to handle OOM, Bitmap Too large exception

* removed unused imports, handled possible exceptions

* Let Fresco handle the downsampling of image

* invalidate in onTransformEnd

* Expose an interface TransformationListener in ZoomableDraweeView to listen to transformation change end

* removed photoView dependency

* removed unused imports in ZoomableActivity

* Bugfix, expand/collapse

* changed functio name
