fpga: Align build process for all targets

- All RFNoC capable targets now require rfnoc_image_builder to be built
- `make help` is updated for all targets to provide more useful and
  up-to-date information
- The FPGA manual is also updated
- All checked-in build artifacts are now removed from git
- axi_ram_fifo.yml is updated to provide include path information
  (required for building N3xx BIST images, which use this)
