[XLA:CPU] Add an in-place implementation of fused-dynamic-update-slice.
This implementation, which applies when a loop-fusion node's root is a
dynamic-update-slice whose input operand and output share the same
buffer slice, is much faster than the out-of-place implementation.
This patch also unifies the implementation of the CPU and GPU versions
of this algorithm.
