While fixing bug 59433 I noticed some additional issues outlined below:
AVDepthData:
* Renamed **non** static `Create` methods because `Create` only
makes sense with the **Static** method in this context. Also
by renaming the methods we are now closer to the names that
swift uses.
* Kept descriptive method names in favor of self-documenting code.
`Convert`, `Apply` and `Replace` do not fully give us the intent
of the method.
* Added a convenience `Create` static method that takes a
`CGImageAuxiliaryDataInfo`.
* AvailableDepthDataTypes is now an array of `CVPixelFormatType` instead
of a `NSNumber` array (The aactual fix for bug 59433).
ImageIO:
* Refactored `CGImageAuxiliaryDataInfo` to be a `StrongDictionary` in order
to avoid most of the manual code and also to avoid reimplementing
the `ToDictionary` method (which contained a subtle bug).
* Adjusted code to reflect the above change.
* Added missing `.ctor (IntPtr, bool)` to `CGImageMetadata` so the class
is able to be created by our `Runtime.Get*`.
* Simplified `CopyAuxiliaryDataInfo` method by using `CGImageAuxiliaryDataInfo`
as a `DictionaryContainer`.
Tests:
* Added `xamarinmonkey.heic` which is an image that contains depth data needed
to test above changes.
* Adds `AVDepthDataTests` that touches most of the changes listed here.
