LibWeb: Make DecodedImageData an abstract class The existing implementation moves down into a new subclass called AnimatedBitmapDecodedImageData. The purpose of this change is to create an extension point where we can plug in an SVG renderer. :^)

LibGfx+LibWeb: Add ImmutableBitmap for images bitmap caching in painter Before this change, we used Gfx::Bitmap to represent both decoded images that are not going to be mutated and bitmaps corresponding to canvases that could be mutated. This change introduces a wrapper for bitmaps that are not going to be mutated, so the painter could do caching: texture caching in the case of GPU painter and potentially scaled bitmap caching in the case of CPU painter.

LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

LibWeb: Make HTML::DecodedImageData to be GC-allocated This change fixes GC-leak caused by following mutual dependency: - SVGDecodedImageData owns JS::Handle for Page. - SVGDecodedImageData is owned by visited objects. by making everything inherited from HTML::DecodedImageData and ListOfAvailableImages to be GC-allocated. Generally, if visited object has a handle, very likely we leak everything visited from object in a handle.
