Optimize I/O code using Okio - part 2 (#4372)

- Read license resource using Okio inside a coroutine (instead of the
main thread) in `LicenseActivity`
- Use Okio and its buffer system to copy ContentProvider streams and
files to a temporary file in `MediaUploader.prepareMedia()`
- Properly close the input file after copying it to a temporary file in
`MediaUploader.prepareMedia()`
- Properly close sink in case of null body source during file copy in
`Uri.copyToFolder()` in `DraftHelper.kt`
- Add comment explaining the current value of `DEFAULT_CHUNK_SIZE` in
`UriRequestBody.kt` and indent the file properly
- Replace hardcoded `Charset` and `Int` byte size with the proper
constants, and align the `hashCode()` implementation with other
`BitmapTransformation` implementations in
`CompositeWithOpaqueBackground`
- Properly close `InputStream` in case of error during Bitmap size
decoding in `getImageSquarePixels()`
- return `Int` instead of `Long` in `getImageSquarePixels()`, since the
current code simply converts the `Int` result to a `Long` _after_
multiplication and not before (and `Int.MAX_VALUE` is already way above
the maximum number of pixels a decoded Bitmap could return)
- Simplify `getImageOrientation()`
- Add explicit dependency to the Okio library and upgrade it to its
latest version.
