Tools.json CallList needs feature to skip when target exists

Tools.json CallList needs feature to skip when target exists.

With current setup it will skip installing upgraded plugin:

"autoDeleteAfterInstall": true,
"skipIfRunnableExists": true

But it needs to skip install in a different way instead:

"callList": [
    {
        "skipIfTargetAlreadyExisted": true,
        "call": "{TOOLS_DIR}/blender-3.4.1-windows-x64/blender.exe",
        "callArgs": {
            "--background": "",
            "--python-expr": "import bpy; import os; fp=os.path.normpath('{THIS_DIR}/{TOOLS_DIR}/io_mesh_w3d.zip'); bpy.ops.preferences.addon_install(overwrite=True, filepath=fp)"
        }
    }
]
