  [mlir][xegpu] Add support for accessing the default order of a layout.  (#184451)

Currently, `getOrder` returns null if the user does not provide an
`order` in xegpu layout. This behavior is undesirable when coupled with
utility functions that work on top of layouts (like `isTransposeOf`).
This PR introduce a `getEffectiveOrder` which always returns the true
order, even if user decides to omit it.
