Separate InputSplitter for transforming whole cells
This allows cell magics to include blank lines once again (closes
#3178).
InteractiveShell now has two input splitters:
- `input_splitter` is used to determine when a block of input is complete, so you can use a cell magic in the terminal by leaving a blank line at the end.
- `input_transformer_manager` is used to transform whole cells, so cell magics affect the whole of their cell.
I removed the similar concept of 'input modes' for InputSplitter, because it was bound to get conflated, and it made the code rather hard to follow.
