Refactor DepthStencilState. TODO: add validation tests
- defaults to depth and stencil tests off - whether or not depth and stencil tests are enabled is inferred from the comparison functions and stencil operations - only one stencil reference. D3D12 does not support separate references - change SetDepthWriteMode to SetDepthWriteEnabled and use a bool instead of enum - Create PersistentPipelineState class for OpenGL backend with simple state tracking - Add validation so DepthStencilState properties are only set once - Update API usage in HelloDepthStencil - refactor tracking of the DepthStencilState in the Metal backend - validate that compute pipeline does not have a depth stencil state
