Message : GN: Componentize D3D format tables. These tables are used by both the GL and D3D11 back-ends. Also moves them to renderer_utils to be in a shared place. Bug: angleproject:3943 Change-Id: I1f5d79842396a87e795547fa03c6855d6f9c5e9a Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2405805 Commit-Queue: Jamie Madill <jmadill@chromium.org> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Geoff Lang <geofflang@chromium.org>

// using it as a texture, a render target, and sampling from it in the shader. It
// checks this against our speed-optimized baked tables, and validates they would
// give the same result.
// TODO(jmadill): Find out why in 9_3, some format queries return an error.
// The error seems to appear for formats that are not supported on 9_3.
