  Log Message:
  -----------
  [MLIR][DLTI][Transform] Introduce transform.dlti.query - 2nd attempt (#102652)

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
`ModuleOp`s but also on any ancestor op that has an appropriate DLTI
attribute.
