Revert "Adds destroy handling for simple objects without new backend changes yet."

This reverts commit 9901c710d1f834fd3e98356f0842553e1ac4afb2.

Reason for revert: Breaking dawn roll due to include in ShaderMock

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
>
