This PR adds a new attribute to the xegpu dialect called xegpu.range.
One use case of this attribute can be to attach subgroup_id_range to
scf.if of to drive the execution.
This PR adds initial skeleton implementation for lowering
ConvertLayoutOp. It currently only supports cases where SLM is not
needed.

This PR allows load_nd/store_nd/prefetch_nd to take an additional offset
operand.
It is based on this PR https://github.com/llvm/llvm-project/pull/148335.
Now user can create a nd_tdesc with no offset, and instead set the
offset with the load_nd operation.
This PR introduces support for `scf::ForOp`, `scf::WhileOp`, `scf::If`,
and `scf::Condition` within the workgroup-subgroup-distribution pass,
leveraging the `SCFStructuralTypeConversionsAndLegality`.
This PR adds the XeGPU workgroup (wg) to subgroup (sg) pass. The wg to
sg pass transforms the xegpu wg level operations to subgroup operations
based on the sg_layout and sg_data attribute. The PR adds transformation
patterns for following Ops
1. CreateNdDesc
2. LoadNd
3. StoreNd
4. PrefetchNd
5. UpdateNdOffset
6. Dpas
