[GPU Process] Add the class 'SourceImage' to represent variants of image
https://bugs.webkit.org/show_bug.cgi?id=235467

Reviewed by Cameron McCormack.

Source/WebCore:

Before the existence of GPUProcess we used to do some drawing on an
ImageBuffer, get a NativeImage from the ImageBuffer and then use this
NativeImage. With GPUProces, this will require bouncing the NativeImage
between WebProcess and GPUProcess at least two times. To make this scenario
efficient, a new class called 'SourceImage' will be introduced. The purpose
of this class is to provide a new level of abstraction for the images
such that no conversion is needed before the actual use.

Replace FEImage::SourceImage with a new class named 'SourceImage'. Let
the new class handle the encoding and decoding and the conversion from
NativeImage to ImageBuffer and vice versa.

Make Recorder::recordResourceUse() returns a boolean which indicates
whether the resource can be cached for later replay or not.
