1. [MLIR][DLTI][Transform] Introduce transform.dlti.query …

   This transform op makes it possible to query attributes associated to
   IR by means of the DLTI dialect.
   
   The op takes both a `key` and a target `op` to perform the query at. Facility
   functions automatically find the closest ancestor op which defines the
   appropriate DLTI interface or has an attribute implementing a DLTI interface.
   By default the lookup uses the data layout interfaces of DLTI. If the optional
   `device` parameter is provided, the lookup happens with respect to the
   interfaces for TargetSystemSpec and TargetDeviceSpec.
   
   This op uses new free-standing functions in the `dlti` namespace to not
   only look up specifications via the DataLayoutSpecOpInterface and on ModuleOps
   but also on any ancestor op that has an appropriate DLTI attribute.
