[MLIR][XeGPU] Adding XeGPU 2d block operators (#85804) 
This PR adds XeGPU 2D block operators. It contains:
1. TensorDescType and TensorDescAttr definitions
2. MemoryScopeAttr and CacheHintAttr definitions which are used by
TensorDescAttr.
3. CreateNdDescOp, PrefetchNdOp, LoadNdOp, and StoreNdOp definitions,
and their corresponding testcases for illustration.

It cherry-picks daebe5c4f27ba140ac8d13abf41e3fe4db72b91a with asan fix.

[MLIR] XeGPU dialect for Intel GPU - core definitions and base classes (#78483) 
This PR follows our previous [RFC
](https://discourse.llvm.org/t/rfc-add-xegpu-dialect-for-intel-gpus/75723)
to add XeGPU dialect definition for Intel GPUs. It contains dialect,
type, attributes and operators definitions, as well as testcases for
semantic checks. The lowering and optimization passes will be issued
with separated passes.
