LibWeb: Don't force HTMLImageElement to have a legacy ImageLoader We achieve this by adding a new Layout::ImageProvider class and having both HTMLImageElement and HTMLObjectElement inherit from it. The HTML spec is vague on how object image loading should work, which is why this first pass is focusing on image elements.

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: Generalize ImageBox and ImagePaintable for any ImageProvider They currently assume the DOM node is an HTMLImageElement with respect to handling the alt attribute. The HTMLInputElement will require the same behavior.

LibWeb: Make ImageBox ask ImageProvider for intrinsic size and ratio This paves the way for ImageProvider to have something vector-based underneath. :^)

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
