What does this PR do?

This PR allows users to pass the device to processor call and get all inputs in the requested device. Currently the device arg is used only in fast image/video processors. But users get confused by the following case

inputs = processor(images, text, device='cuda', return_tensors='pt')

# Before the PR
print(inputs.input_ids.device) # "cpu"
print(inputs.pixel_values.device) # "cuda"

# After the PR
print(inputs.input_ids.device) # "cuda"
print(inputs.pixel_values.device) # "cuda

Now we will allow either to pass device and get all inputs initialized already on device, or to move to device manually by inputs.to(device)

Fixes #42722
