Submodules: Only fetch required (#5182, closes #5105) + Non-shallow fallback (hotfix)

* Retry updating submodules non-shallow if shallow clone fails (master hotfix)
* Add `PLUGIN_LIST` support to CheckSubmodules (#5105)
* Remove `SKIP_SUBMODULES` switch (it's redundant to specifying `PLUGIN_LIST`)
* Add `NO_SHALLOW_CLONE` switch
