Vectorize TensorPrimitives.Sin/Cos (#98194)

* Vectorize TensorPrimitives.Sin/Cos

* Clean up implementation

* Split Sin/CosOperator into separate float/double types

* Manually inline POLY_EVAL_ODD_*

And make a few things more consistent

* Address remaining PR feedback

Also move some tests to outerloop to decrease inner loop testing time
