This is a reland of 9901c710d1f834fd3e98356f0842553e1ac4afb2 Original change's description: > Adds destroy handling for simple objects without new backend changes yet. > > Simple objects are defined here as objects that do not already have a destroy or destroy-like API available. They include: > - BindGroups > - ComputePipelines > - PipelineLayouts > - RenderPipelines > - Samplers > - ShaderModules > - SwapChains > > Changes include: > - Adds necessary constructors for testing and caching > - Adding mock objects, mock constructors, and tests > > Bug: dawn:628 > Change-Id: I26a5e37bc5580b9064db299a75ef1243521b266a > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/65864 > Commit-Queue: Loko Kung <lokokung@google.com> > Reviewed-by: Austin Eng <enga@chromium.org> Bug: dawn:628 Change-Id: I19492ad6b1660e205d123b2d1fdf53c772564cfe Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/67961 Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Loko Kung <lokokung@google.com>
