Revert of Add a origin clean flag in ImageBitmap class (patchset #14 id:260001 of https://codereview.chromium.org/1532473002/ )

Reason for revert:
Seems to have broken Oilpan builds:
https://build.chromium.org/p/chromium.webkit/buildstatus?builder=WebKit%20Mac%20Oilpan&number=28566
https://build.chromium.org/p/chromium.webkit/buildstatus?builder=WebKit%20Linux%20Oilpan%20Builder&number=100

Original issue's description:
> Add a origin clean flag in ImageBitmap class
>
> This CL adds a origin clean flag, such that in the case when the source
> of the ImageBitmap contains cross-origin content, we can simply set this
> flag instead of reject the promise.
