Description of Change

First needs #30002 to be merged, builds on top of that PR.

This PR introduces image compression for MediaPicker. This works for images only when picked from the gallery as well as when captured through the camera. The quality of the image can be controlled by setting the newly introduced CompressionQuality property in the MediaPickerOptions object.

Additionally, this PR introduces a way to limit the size of the image that is returned by influencing the dimensions. On the MediaPickerOptions object, two properties were added to control the size of the image: MaximumWidth and MaximumHeight. Based on the values, the picked/captured image will be resized to fit within the specified dimensions while maintaining the aspect ratio.

As a bonus the Essentials Sample looks a bit nicer and is updated to play with all these new features.
