fpga: lib: add handshake to replace FIFO for ctrlport CDC
The clock crossing of the ctrlport used FIFOs to transfer requests and responses
between clock domains. This commit adds a handshake based on the pulse
synchronizer to reduce the resource usage for ctrlport clock domain crossing.
Data is stored in a single register while the pulse synchronizer handles the
signaling of valid flags.
