TRT's opconverter unit tests are changed in this PR to use unified memory when creating test tensors. This simplifies BuildAndRun, since copying the data between GPU and host is done automatically by the driver.
Switching to unified memory is achieved by moving the AsTensor and ConstructTensor functions inside the OpConverterTest class and using GpuManagedAllocator in them.
This PR is based on #38118, please review that first.
