On Linux (and Windows) we should not create toplevel files (README.md
etc) or directories (doc/, scripts/ etc).
On macOS, move the whole Devel package contents into the app bundle,
because that is installed toplevel in the Qt installers, and we
shouldn't even create include/, lib/ or any other directory at the
toplevel at all.
Since the prefix path must now point to the Resources folder inside the
app bundle, adapt build_plugin.py to also accept --qtc-path pointing to
the app bundle (Qt Creator.app) itself, and also to the app bundles
parent directory. Adapt the Qt Creator plugin project template
similarly.
