This fixes a large number of SkSL namespaces which were labeled as if
they were anonymous, and also a handful of other mislabeled namespaces.
Missing namespace-end comments have been added throughout.
A number of diffs are just indentation-related (adjusting 1- or 3-
space indents to 2-space).

The callback lets the caller know when the data uploads to the texture
from the create call are finished. This is important since the caller
cannot delete the backend texture till the gpu is finished on vulkan
and d3d.
This change also removes the hard sync in vulkan during creation.

The major changes on a higher lever are:
1) The majority of all copies now go through GrSurfaceProxy::Copy which
takes in a proxy and returns a new one with the data copied to it. This
is the most common use case within Ganesh.
2) The backend copy calls no longer do draws, require origins to be the
same, and won't do any swizzling or adjustment of subrects. They are
all implemented to be dumb copy this data to this other spot.
3) The GrSurfaceContext copy call has now been moved to priv and renamed
copyNoDraw, and a new priv copyAsDraw was added to GrRenderTargetContext.
4) WritePixels and ReplaceRenderTarget both need to specifiy the destination
of copies. They are the only users (besides the GrSurfaceProxy::Copy) which
call the priv methods on GrSurfaceContext.
