tcl: Add support for NDS V5 target and xc7/Corvette-F1

The "Corvette-F1" is an Arduino-compatible evaluation platform,
which fully supports AndesCore. The board has FTDI FT2232 to
connected to FPGA's JTAG interface.

The "ADP-XC7KFF676" is a development and prototyping board that
provides capacity for evaluation of AndesCore processors.
It works with AICE in-circuit debugging tools.

This patch also include target/nds32v5.cfg to support AndesCore
N22/N25F and AndeShape Platform AE250.
