  [mlir][spirv] Add support for SPV_ARM_graph extension - part 1 (#151934)

This is the first patch to add support for the SPV_ARM_graph SPIR-V
extension to MLIR’s SPIR-V dialect. The extension introduces a new Graph
abstraction for expressing dataflow computations over full resources.

The part 1 implementation includes:

- A new `GraphType`, modeled similarly to `FunctionType`, for typed
graph signatures.
- New operations in the `spirv.arm` namespace:
  - `spirv.arm.Graph`
  - `spirv.arm.GraphEntryPoint`
  - `spirv.arm.GraphConstant`
  - `spirv.arm.GraphOutput`
-  Verifier and VCE updates to properly gate usage under SPV_ARM_graph.
-  Tests covering parsing and verification.

Graphs currently support only SPV_ARM_tensors, but are designed to
generalize to other resource types, such as images.

Spec: KhronosGroup/SPIRV-Registry#346
RFC:
