This CL is mostly mechanical. It:
replaces "src/gpu/GrSurfaceDrawContext.h" #includes with
"src/gpu/v1/SurfaceDrawContext_v1.h" and reorders
replaces "class GrSurfaceDrawContext;" with
"namespace skgpu { namespace v1 { class SurfaceDrawContext; }}"
replaces "GrSurfaceDrawContext*" with "auto" where possible
replaces "rtc" with "sdc"
replaces "surfaceDrawContext" with "sdc"
replaces GrSurfaceDrawContext with skgpu::v1::SurfaceDrawContext
reflows parameters as needed
This CL does not try to:
make skgpu::v1::SurfaceDrawContext V1-only
minimize the skgpu and/or skgpu::v1 prefixes
Those two tasks will be accomplished in follow up CLs. This CL is just trying to get the bulk of the mechanical changes comprehensibly landed.
