[CPU][x86] add support for sink input of SDPA (#32374)
### Details:
- *extend the softmax kernel API to make it support sink input*
- *in the reference implementation of sink input, there are 3
operations, **cat,** **softmax**, **drop**, because **cat** and **drop**
will make attention_weight shape changed, so modify softmax API maybe a
good way to reduce memory allocation and movement*
