This adds the NIPC parameter, which configures support for processing
multiple items or samples per clock cycle. With this enabled, the FFT
block can process at rates higher than 250 MSPS, such as 500 MSPS and
beyond.

This replaces the legacy RFNoC FFT block with a new one of the same
name that includes a superset of the original features. New features
include cyclic prefix insertion or removal and FFT sizes up to 64k.
