Commit Message

Reduce CUDA context push/pop overhead (#642)

* Set CUDA context at SlangPy entry points for reduced overhead

  - Add set_cuda_context_current() wrapper in Device class
  - Call setCudaContextCurrent() in NativeCallData::exec() before kernel
  execution
  - Add Python binding for manual context control
  - Update tests to set CUDA context before test execution

  Works with slang-rhi CUDA context optimization to eliminate per-call
  push/pop overhead by setting context once at entry points.

* Simplify the ContextScope push/pop

* Address review feedback: restore push/pop in present()/configure(), keep cuCtxGetCurrent optimization
