Brian Salomon f9b0042423 Expose ManagedBackendTexture from BackendTextureImageFactory.
Add helper to create self-managed BackendTexture-backed SkSurface for
tests using MBET.

GrGpu::createTestingOnlyBackendRenderTarget supports protected.

Make SkSurfaceCharacterization tests use self-managed SkSurface
factories and a use case of MakeFromBackendTextureAsRenderTarget is
removed.

Use self-managed BackendTexture-backed SkSurface factory in DM sinks and
in fm.
