Dimitar Tachev a94ec9946f Improve ImageAsset scaling (#5110)
* Do not depend on current device screen while calculating Image Asset size.

* Scale the image asset to the exact requested size.

* Process image assets natively, pass keepAspectRatio based on the stretch property and Asset options.

* Fixed the splashscreen resource name as it cannot be read when containing a dot.

* Updated the Image Asset scale and rotate logic based on the Native one.

* Make the ImageAsset size more important than the Image decode size as its more specific.

* Fixed tslint errors.

* Added filePath support in the ImageAsset constructor for iOS in order to unify it with the Android implementation, support for relative files and file not found support errors.

* Added unit tests for ImageAssets.

* Added a sample app for UI testing of image-view with ImageAsset src.

* chore: apply PR comments
