First batch of files in metadata that Audio Player depends on:
- metadata_provider.m.js
- image_orientation_unittest.m.js
- image_orientation.js
- metadata_request.js

Note on the image_orientation_unittest:
assertArrayEquals() andassertDeepEquals() now check for the type, so
changed to use Uint8ClampedArray in the expected value.
