Update DefaultNativeMemoryChunkPoolParams

Updates default memory pool parameters to avoid failing on devices having memory limit as: 0-4MB, 32-~66MB.

GIF decoder

Adds GIF decoder (force animated GIFs to be rendered as static images).

New API: GetFileCachePath

By design, when we call PrefetchToDiskCacheAsync method, the image is downloaded and written to the staging area (in memory) and then a background task is initialized to actually writes the file to disk. GetFileCachePath method was added to allow waiting for the file creation and returns its local path.

Update HTTP redirect handling

In http redirect handling, Fresco (Android) doesn't allow the next uri to have the same scheme as the original one (for example, http://domain1.com -> http://domain2.com will always fail). This changes the default behavior to allow more flexibity in http redirect requests.

Update DispatcherHelpers

• Use CoreApplication.MainView.Dispatcher instead of CoreApplication.MainView.CoreWindow.Dispatcher in DispatcherHelpers for scenarios like background activation (valid dispatcher is on the CoreApplicationView, not necessarily on the CoreWindow).
• You can now pass an optional dispatcher when fetching images using FetchEncodedBitmapImageAsync and FetchDecodedBitmapImageAsync methods (helpful in multi-window scenario).

New features and bug fixes

• Fetch local images as BitmapImage instead of WriteableBitmap.
• Fetch images from FutureAccessList urn (urn:future-access-list:{}).
• Several bug fixes related to invalid Uri handling.
