[mlir][acc] Introduce acc data bounds accessors (#156545)

Add acc.get_lowerbound, acc.get_upperbound, acc.get_stride, and
acc.get_extent operations to extract information from acc bounds.

This simplifies the arguments needed for recipes when handling slices
and makes bound information consistent with data clauses. Update recipe
documentation to clarify argument ordering and add examples
demonstrating slice handling with bounds arguments.
