Implements a workaround for HSDES#14014414195. Note that this change deviates heavily from the workaround suggested in the HSDES, since all of the suggestions are either costly at runtime or outright non-compliant, so they would require us to apply the workaround selectively for affected applications. Instead of adding hacks to the compiler that manually implement the LOD computation of 3D texturing operations in the shader, initialize an extra sampler state structure in the driver that has anisotropic filtering forced off, and use it instead of the normal sampler state structure whenever a 3D texture is bound to the same sampler unit.
