Revert "Feed all top-level GPU accessors through skgpu::BaseDevice"

This reverts commit 5de8b1950422d002f9c1a1ebdf545364d7d1dcfe.

Reason for revert: blocking Android roll

Original change's description:
> Feed all top-level GPU accessors through skgpu::BaseDevice
>
> This pulls the GPU-specific accessors off of SkCanvas and SkDevice - moving them all to skgpu::BaseDevice and SkCanvasPriv.
>
> This will allow us to more easily change the gpu class hierarchy (esp. changing GrSurfaceDrawContext to skgpu::v1:SurfaceDrawContext) w/o churning the public API.
>
