  Log Message:
  -----------
  Reimplementing target description concept using DLTI attribute (#92138)

and Interfaces. This is a newer implementation of PR
https://github.com/llvm/llvm-project/pull/85141 and
[RFC](https://discourse.llvm.org/t/rfc-target-description-and-cost-model-in-mlir/76990)
by considering reviews and comments on the original PR.

As an example of attributes supported by this commit:

```
module attributes {
   dlti.target_system_spec =
     #dlti.target_device_spec<
       #dlti.dl_entry<"dlti.device_id", 0: ui32>,
       #dlti.dl_entry<"dlti.device_type", "CPU">,
       #dlti.dl_entry<"dlti.L1_cache_size_in_bytes", 8192 : ui32>>,
     #dlti.target_device_spec <
       #dlti.dl_entry<"dlti.device_id", 1: ui32>,
       #dlti.dl_entry<"dlti.device_type", "GPU">,
       #dlti.dl_entry<"dlti.max_vector_op_width", 64 : ui32>>,
    #dlti.target_device_spec <
       #dlti.dl_entry<"dlti.device_id", 2: ui32>,
       #dlti.dl_entry<"dlti.device_type", "XPU">>>
}
