  [MLIR][XeGPU] Clean up the temporary layout usage in XeGPU test (#195739)

This PR cleans up the XeGPU test to remove the temporary layout usage.
All distribution and unrolling tests now don't use temporary layout from
the operation and TensorDescriptor, since the recovery process won't
honor the temporary layout and only depends on the anchor layout.
It also refactors the layout function implementation by removing
recursive loops in getDistributeLayoutAttr(), and fixes two issues
surfaced from the test clean up: adding layout recovery support for
Extract/Insert op and tensor descriptor type.
