[RISCV][TTI] Model the cost of insert/extractelt when the vector split into multiple register group and idx exceed single group. (#118401)
This patch implements the cost when the size of the vector need to split
into multiple groups and the index exceed single vector group.
For extract element, we need to store split vectors to stack and load
the target element.
For insert element, we need to store split vectors to stack and store
the target element and load vectors back.
After this patch, the cost of insert/extract element will close to the
generated assembly.
