Why would IO pins be tied to VCC or GND with 0 Ohm resistor on FPGA Dev Board?
The pinout sheet from Intel shows these to be generic I/O, no config or reference function (at least for these two, you will need to look up the other two also.) So ...
1.) They are simply for debug …

Trying to find out the voltage threshold for input of a GPIO pin in an FPGA development board
will find entries like:
set_instance_assignment -name IO_STANDARD "3.3-V LVTTL" -to i_serIn
set_instance_assignment -name CURRENT_STRENGTH_NEW 8MA -to o_LED[0]
and so forth to let you know what that FPGA …
