Refactor TransformationException.createForCodec method overloads.

* Overload added `(cause, errorCode, isVideo, isDecoder, details)`,
where `details` is a string of values to be added to the error message
of the `TransformationException`.
* Overload with `MediaFormat` and `mediaCodecName` moved to
`DefaultCodec`, because all usages of that overload were from
`DefaultCodec`, and this allows a simplified API because of internally
stored values.
* `mediaCodecName` removed from overload that takes a `Format`.
* Reordered `createForCodec` parameters.
