Subject: [PATCH 1/2] [MLIR] SPIRV Target Attribute
Create SPIRV Target Attribute to enable GPU compilation pipeline.
The Target Attribute is modeled after the existing spriv.target_env
Plan is to use this new attribute to enable GPU compilation pipeline
for OpenCL kernels only.
The changes do not impact Vulkan shaders using milr-vulkan-runner.
New GPU Dialect transform pass spirv-attach-target is implemented for
attaching attribute from CLI.
gpu-module-to-binary pass now works with GPU module that has SPIRV module
with OpenCL kernel functions inside.
