projects/xcvr_wizard/scripts: Fix HDL for XCVR automation in TB

[hadarauelena]

PR Description

Added the new script adi_xcvr_xilinx.tcl under the new scripts folder in the xcvr_wizard project. Updated the adi_xcvr_project function to allow sourcing the script directly from the testbench repository.
Updated adi_xcvr_project function to accept the board name as a new optional parameter. If the parameter is provided, the script will use that value; if not, it will be automatically extracted from the directory name.
