This allocates the buffer on a per-device basis and enables ray
tracing on devices that support it when given a kernel with ray
tracing calls.

encodeMulRegVal() makes extensive use of encodeAluAdd().
The following problems are addressed:
* encodeAluAdd() performs an addition and saves the
calculated result to the first register. Saving the
result to the first register clears the calculated result.
* An array of MI_MATH buffers is setup prior to performing a
series of encodeAluAdd()'s where the same registers are
reused for the calculations. For calculated results to be
carried over from one encodeAluAdd() operation to subsequent
encodeAluAdd() operations, the MI_MATH buffer needs to be
setup per encodeAluAdd().
Create EncodeMath<Family>::addition() to reserve a MI_MATH buffer
and performs the addition by calling encodeAluAdd().
Modify encodeAluAdd() to save calculated result to a third
register. Then, after EncodeMath<Family>::addition() is called
in encodeMulRegVal(), copy the calculated result from the result
register to the first register from the EncodeMath<Family>::addition()
operation. This will allow the calculated value to be carried over
to subsequent addition operations.
