fix: use open_component instead of open_project

Create HLS components from the auto-generated Tcl script
instead of just open_project/open_solution flow.  Without
the use of open_project -ide vitis or open_component, you
create "see" the corresponding HLS component in the Vitis
Unified IDE (and therefore can't use the set of support
tools within Vitis IDE).
