LibWeb: Start fleshing out HTML "image requests" and "image data" This patch adds HTML::ImageRequest and HTML::DecodedImageData. The latter had to use a different name than "ImageData", as there is already an IDL-exposed ImageData class in HTML.

LibWeb: Have ImageProvider bitmap getter take optional size argument This allows the painting subsystem to request a bitmap with the exact size needed for painting, instead of being limited to "just give me a bitmap" (which was perfectly enough for raster images, but not for vector graphics).

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.

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

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.
