e6f360b0 - [MLIR][XeGPU] Allow load/store/prefetch uses [memref+offset] instead of tdesc (#150576)

[MLIR][XeGPU] Allow load/store/prefetch uses [memref+offset] instead of tdesc (#150576) Add variant of load/store/prefetch to allow offset. The new xegpu.load variant accepts memref+offset, and the existing tdesc operand will be removed in the future PR. The semantics are combination of "creating scattered_tdesc + xegpu.load with scattered_tdesc". The current xegpu.load accepts tdesc operand, which encapsulates "memref+offset". This PR "fold" "memref+offset" directly to xegpu.load replacing "tdesc". Create_tdesc will be removed as scatter_tdesc only contains base address after offsets being taken away, so there is no point to keep it. ```mlir // wi level code example %2 = xegpu.load %src[%offsets], %mask <{chunk_size = 2}> : ui64, vector<1xindex>, vector<1xi1> -> vector<2xf32> xegpu.store %val, %src[%offsets], %mask: vector<1xf16>, memref<?xf16>, vector<1xindex>, vector<1xi1> xegpu.prefetch %src[%0] : ui64, vector<1xindex> ```
