As mentioned in the title, What is the meaning of package length and pcb length in pin reference of XEM7305? What is the difference between package length and pcb length?
In my thinking,
Package length: length from pad of spartan-7 bare-die to pad of package
PCB length: length from pad of package to connector of XEM7305 board

Yes, you are correct. The package lengths are reported from the Xilinx software. We have included them in Pins for convenience.
