Investigate ImageBitmap->GetImageWithAlphaDisposition with extended sRGB

Project Member Reported by zakerinasab@chromium.org, Mar 2 2018 
GetImageWithAlphaDisposition is a static utility function in ImageBitmap.cpp. There are two things that need more consideration when extended sRGB is introduced to the proposal and supported by Skia:

- The unpremul always happens in gamma encoded space.
- For premul, sRGB gamma curve is avoided by comparing the image color space to sRGB.

This should work fine when Skia supports ex-sRGB. The code now has changed to draw on a canvas for premul and use readPixels() for unpremul.
