Apply image transformation for thumbnails loaded by loadDetachedImage.

This change will fix 2 parts where we had wrong image orientation,
when there's EXIF image rotation/transfomration info.
1. Tooltip thumbnail when an image is dragged in Files app.
2. Low-density image tentatively shown in Gallery app.

The drag thumbnail is changed to use the CANVAS mode,
because the IMAGE mode still doesn't work correctly.

For testing, we can use images downloaded from:
https://github.com/recurser/exif-orientation-examples

> (1) Prepare an image file with non-zero EXIF orientation.
"non-zero" here is inaccurate. The correct condition is "Orientation value other than 1".

Change the drag thumbnail rendering back to IMAGE mode to fix a regression.

Here is the change that caused  crbug.com/681796 . This changelist partially reverts its change that affected drag thumbnail rendering.
https://codereview.chromium.org/2630283002/

When an item is rendered in CANVAS mode, some metadata field are not
filled unlike IMAGE mode. It causes unexpected execution path and
outputs an error when clicking on a non-image file whose thumbnail is
not yet cached.

Take the rotation information from the right source.

The transform data may be stored in thumbnail instead of media.
The constructor of ThumbnailLoader has the logic to detect the both.

This is a follow-up of 2691933007.
