fix(gpu): allow VS-expanded primitives in D3D12 pipeline cache

Browse Source 
TranslateAnalyzedShader and CreateD3D12Pipeline assumed host vertex type was only kVertex for non-tessellation paths. Point/rectangle list expansion uses kPointListAsTriangleStrip and kRectangleListAsTriangleStrip while still emitting a vertex shader — accept those types for logging and PSO creation.
