[mlir] Remove unused includes (NFC) (#147455) 
These are identified by misc-include-cleaner.  I've filtered out those
that break builds.  Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.

[MLIR][GPU] Use arith instead of index for subgroup_id (#137843) 
Trying to simplify situation by using `arith` dialect instead of `index`
in the rewriting of `gpu.subgroup_id`.

[MLIR][GPU] Add a pattern to rewrite gpu.subgroup_id (#137671) 
This patch impelemnts a rewrite pattern for transforming
`gpu.subgroup_id` to:
```
subgroup_id = linearized_thread_id / gpu.subgroup_size
```

where:
```
linearized_thread_id = thread_id.x + block_dim.x * (thread_id.y + block_dim.y * thread_id.z)
```
