Add pre-compile hook to generate platform designer system

[tvannoy]

It is quite annoying having to open Platform Designer and generate HDL when cloning these projects. I'm pretty sure we can add a pre-compile tcl hook in Quartus to automatically generate the Platform Designer system before compiling the project.

Doing this could have the potential downside of always generating the Platform Designer HDL, which can be time consuming. It'd be nice if we could detect if the HDL has already been generated.

Is the purpose of this just for immediately after cloning a project or during development of Platform Designer components as well? If it is just for immediately after cloning and then updates to the system are still going to need to be manually regenerated I could probably throw together a tcl script for that

My thinking is that it'd be nice to have Quartus generate the Platform Designer system when hitting the compile button if it hasn't already been generated. I recall seeing some setting in Quartus itself that alluded to doing that, but I haven't tested it out.

So Quartus would regenerate every time there has been a Platform Designer change that hasn't been generated, ideally. During development of a Platform Designer system, I don't think we'd ever run into needing to regenerate as we would be doing it manually anyway.
