windows: Add installer build

For distribution of Radicle on Windows machines, Windows Installer
provides a well-known solution, that comes built in to the operating
system. It also integrates with the Windows package manager WinGet.

Provide an initial version of an `*.msi` build, and integrate it into
GitHub actions to allow downloads via build artifacts.
