VCU118 - Corundum: Updated scripts to solve critical warning related to system_top

[IstvanZsSzekely]

PR Description

All projects are expected to have the same system top module named system_top.
Current Corundum network stack uses an alternative system top module name, which has a different name from system_top. Because of this, Vivado reports a critical warning.
The changes in this scripts don't affect existing projects, it adds an optional parameter to adi_project_files, which allows us to change the system_top module if needed.
