LibGfx: Introduce a new Gfx::Painter with a Skia backend This new painter is written with a virtual interface from the start, and we begin with a Skia backend. This patch adds enough to support our basic 2D HTML canvas usecase.

LibWeb+LibGfx: Use GPU backend for <canvas> This is implemented by using a GPU-accelerated surface for <canvas> when a GPU context is available. A side effect of this change is that all canvas modifications have to be performed through Gfx::Painter, and whenever its content has to be accessed, we need to take a snapshot of the corresponding GPU surface. A new DrawPaintingSurface display list command is introduced to allow cheap blitting of canvas content without having to read GPU surface content into RAM.

LibGfx+LibWeb: Cache SkImage in ImmutableBitmap By caching the SkImage that is reused across repaints, we allow Skia t optimize GPU texture caching. ImmutableBitmap is chosen to own the SkImage because it guarantees that the underlying pixels cannot be modified. This is not the case for Gfx::Bitmap, where invalidating the SkImage would be challenging since it exposes pointers to underlying data through methods like scanline().

LibGfx+LibWeb: Add new Path class with Skia backend, use for 2D canvas This thing is essentially a wrapper around an SkPath, although we do some indirection via a PathImpl class to keep the door open for alternative rasterizer/path backends in the future. We also update the 2D canvas code, since that was the only code that used Painter+DeprecatedPath, and this allows us to just drop that code instead of temporarily supporting it until the next commit.
