Fixes build warning:
```
WARNING: Project specifies a minimum meson_version '>= 0.48.0' but uses features which were added in newer versions:

```

This commit only adds support within the build system, no further attempt to make it build has been tried.
* mutter: Update the .vapi for libmutter-7
* Fix vapi syntax
* Make it work with mutter-7
* Re-enable PIP plugin
* Fix screenshot code
* Fix type
* Cleanup workspaces sooner
So we don't see the workspace removed animation on login
