Adds dtypes decorators to and allows helper methods in device generic test classes (#26375)
Summary:
- Adds dtypes, dtypesIfCPU, and dtypesIfCUDA decorators.
- Eliminates the need for nontest members to be defined in an inherited base.
- Updates one test to use the decorators and updates TestTorchDeviceType with helpers.
This PR appears to be hanging the ROCm build, which is not entirely surprising. See https://github.com/pytorch/pytorch/issues/26394, which demonstrates that the ROCm build can be hung by commenting out a Python test that was never run on ROCm.
gchanan - what type list, if any, do you want to expose? I imagine most test suites will define their own lists like today. SCALAR_TYPES, QUANTIZED_TYPES, and ALL_TYPES seem reasonable to me. DOCUMENTED_TENSOR_TYPES will be removed, of course.
