+ `RangeAttr` is an attribute that defines a half-open range [start, end).
+ The range is inclusive of the start value and exclusive of the end value.
+ One usage of this attribute can be to specify the subgroup id range.
+ The subgroup id range can be specified using this attribute,
+ and it can be attached to a scf.if op like
+ ```mlir

+ // some operations
+ }{sg_id_range = #xegpu.range<[2, 4]>}
