Chrome would like to perform cpu-side preprocessing for gpu draws in parallel.
They do not want to go through a picture (since they have their own display list format).
The general idea is that we add a new SkDeferredDisplayListRecorder class to
perform all of Ganesh's cpu-side preprocessing ahead of time and in parallel.
The SkDDLRecorder operates like SkPictureRecorder. The user can get an SkCanvas
from the SkDDLRecorder and feed it draw operations. Once finished, the user
calls 'detach' to get an SkDeferredDisplayList. All the work up to and
including the 'detach' call can be done in parallel and will not touch
the GPU. To actually get pixels the client must call SkSurface::draw(SkDDL)
on an SkSurface that is "compatible" with the surface characterization
initially given to the SkDDLMaker.
The surface characterization contains the minimum amount of information Ganesh needs
to know about the ultimate destination in order to perform its cpu-side work
(i.e., caps, width, height, config).

be in an additional CL.
Besides the change to use the type safe classes, we also pull the SurfaceFlags, origin,
samples, out of the descriptor and pass those in directly.

This unused feature complicates MDB.
Chrome compiles locally for me with this CL.

This is the same as https://skia-review.googlesource.com/c/4383/ (Further centralize computation of GrSurface VRAM consumption) but with a suppression for Vulkan in the new test and removal of an assert Chromium was triggering.

Skia's GrTextureProvider currently exposes two APIs for wrapping backend
objects:
* wrapBackendTexture - wraps a texture into a GrTexture. Depending on
flags, this GrTexture can be converted to a GrRenderTarget. Skia
manages the render target objects it may create to provide a render
target for the texture. This allows Skia to create stencil buffers
if needed and manager MSAA resolves.
* wrapBackendRenderTarget - wraps a FBO into a GrRenderTarget. This
object cannot be converted to a GrTexture. Skia does not manage
the render target objects for such a GrRenderTarget, and as such
cannot attach stencil buffers or perform MSAA resolves on the
created GrRenderTarget.
Given these two options, wrapBackendTexture provides more versatility
and allows Skia more room for optimization. Chrome currently uses
wrapBackendTexture for this reason.
While these two functions cover most cases, they do not provide a way
for Skia to wrap a texture into a render target (and gain the MSAA and
stencil buffer management), without also creating a GrTexture. This is
problematic in cases where a texture can be bound to a render target,
but cannot be textured from, as is the case in Chrome's limited support
for GL_TEXTURE_RECTANGLE.
To address this, a new function is created:
* wrapBackendTextureAsRenderTarget - wraps a texture into a
GrRenderTarget. As with wrapBackendTexture, the created render
target objects are fully managed by Skia. Unlike wrapBackendTexture
no GrTexture is created, and the created object will never be
textured from.

Restructure SkGpuDevice creation:
*SkSurfaceProps are optional.
*Use SkSurfaceProps to communicate DF text rather than a flag.
*Tell SkGpuDevice::Create whether RT comes from cache or not.
