Log Message:
-----------
Add an SPI in WKWebView which retrieves image metadata from image data
https://bugs.webkit.org/show_bug.cgi?id=312425
rdar://173955537
Reviewed by Tim Horton.
The SPI getImageMetadata will use the WebContent process to decode the image
data and retrieve the size, the density and the frame count of the image.
