Wen-Heng (Jack) Chung 2cbbc266ec [mlir][gpu] Refactor ConvertGpuLaunchFuncToCudaCalls pass.
Due to similar APIs between CUDA and ROCm (HIP),
ConvertGpuLaunchFuncToCudaCalls pass could be used on both platforms with some
refactoring.

In this commit:

- Migrate ConvertLaunchFuncToCudaCalls from GPUToCUDA to GPUCommon, and rename.
- Rename runtime wrapper APIs be platform-neutral.
- Let GPU binary annotation attribute be specifiable as a PassOption.
- Naming changes within the implementation and tests.

Subsequent patches would introduce ROCm-specific tests and runtime wrapper
APIs.
