The SDC will soon be V1-only. Remove it from the generic testing infrastructure and require each V1-specific GM to explicitly retrieve it. Bug: skia:11837 Change-Id: I4c904b7e333333382062bde4b17a1f9f81bee6a9 Reviewed-on: https://skia-review.googlesource.com/c/skia/+/430425 Commit-Queue: Robert Phillips <robertphillips@google.com> Reviewed-by: Michael Ludwig <michaelludwig@google.com>
