[NFC][GPU] Move LLVMGPUPipelineOptions to iree_gpu dialect (#18458)

This moves `LLVMGPUPipelineOptions` to `Codegen/Dialect/GPU` so that
pipeline options can be set by iree_gpu lowering configuration logic
(like `setMatmulLoweringConfig` in `ConfigUtils.cpp`).

A new attribute `GPUPipelineOptionsAttr` is added, with optional
parameters defined for each existing pipeline option. The assembly of
the pipline attributes has changed, since the options are now part of
the `iree_gpu` dialect. For the purposes of setting user configurations
with transform dialect this PR changes the following:

All pipeline option attributes should now be contained in a single
`#iree_gpu.pipeline_options<>`
- `reorder_workgroups = "none"/"swizzle"/"transpose"` becomes one of the
pipeline options `reorder_workgroups_strategy = None/Swizzle/Transpose`
- `prefetch_shared_memory` becomes the pipeline option
`prefetch_shared_memory = true/false`
- `no_reduce_shared_memory_bank_conflicts` becomes the pipeline option
`no_reduce_shared_memory_bank_conflicts = true/false`

Example:

After this change, the translation_info config dict changes from
```
{reorder_workgroups = "swizzle", prefetch_shared_memory}
```
to
```
{gpu_pipeline_options =
    #iree_gpu.pipeline_options<
        prefetch_shared_memory = true, reorder_workgroups_strategy = Swizzle
    >}
```
