gfx: Rename `WebrenderSurfman` to `RenderingContext` and move to `gfx` (#31184)

This is a small cleanup that moves and renames this class. The rename is
simply because we are exposing a lot about the details of Servo's
rendering in the API and it makes sense to start thinking about
abstracting that away a bit.

This also moves the struct to `gfx`, which does have an effect on
Servo's dependency graph. This adds a new dependency on gfx to
`compositing`, but `compositing` had a transitive dependency on
gfx before through `canvas`.
