fix(windows-installer): add new cleanup script on install (#824)

Issue #, if available:

*Description of changes:*
- Add new script that runs upon installation to cleanup any dangling
Finch VM
- This is needed because earlier versions of Finch's Windows installer
don't clean up properly on uninstall / reinstall
- Even with this change, user's will be prompted to stop limactl on
reinstall if Finch is running. Regardless of which action they choose,
the install script will cleanup any dangling VMs.

*Testing done:*
- Tested locally


- [x] I've reviewed the guidance in CONTRIBUTING.md
