When `WEBP_USE_THREAD` is not defined the assignments of *_SSE and their unsuffixed counterparts may race. Assigning *_SSE directly rather than relying on the unsuffixed values avoids a case where the *_SSE variants may refer to the calling function (i.e., AVX2) resulting in infinite recursion. Defining `WEBP_USE_THREAD` is recommended when decode/encode calls can be made from different threads. Bug: 435213378 Change-Id: Id5549730cb72be99b3014ed8e4e355f3ea988659
