HDRenderPipeline: Fix tangent issue when orthornomalize in Lit.shader

     // Orthonormalize the basis vectors using the Gram-Schmidt process.
     // We assume that the length of the surface normal is sufficiently close to 1.
     // This is use with anisotropic material
-    tangentWS = normalize(tangentWS - dot(tangentWS, normalWS));
+    tangentWS = normalize(tangentWS - dot(tangentWS, normalWS) * normalWS);
