Subject: [PATCH] Add CMake option WITH_STAGED_PLUGINS (ON by default)

- Core plugins remain available once staged (no need to re-build targets, unless source updated or build directory cleared)
- Once plugins are staged, setting WITH_STAGED_PLUGINS to OFF allows for much quicker subsequent builds
- PyQGIS utilities, console and installer are always staged, regardless of WITH_STAGED_PLUGINS
