add the rnote cli to the windows inno build

[Doublonmousse]

CI test on : https://github.com/Doublonmousse/rnote/actions/runs/25228946601

Fixes #1757

TODO

• cleanup the script (does it work with -Dcli=false? I'm not sure whether it fails when failing to copy a file or how to adapt the script more cleanly for this)
• add to path? For now this is in the bin folder, not in the window path

Not sure if it is possible with Inno, but I've seen installers asking whether they can add a path entry to PATH. Would be cool if we could do the same!

Now this works with -Dcli=false calling manually meson.

The only part that doesn't work is the just build-win-installer command if the cli = false option is selected as this invokes

build:
    meson compile ui-cargo-build -C {{ build_folder }}
    meson compile cli-cargo-build -C {{ build_folder }}

and the second command doesn't exist if the cli = false option is selected. It errors with

ERROR: Can't invoke target `cli-cargo-build`: target not found
error: Recipe `build` failed on line 186 with exit code 1

Seems like adding to path as an option is possible: see https://github.com/mentebinaria/retoolkit/blob/f86f5e608836b898da36a3787eb5135d2baef976/src/installer/retoolkit.iss#L214

Updated to include the optional path update in the installer

Waiting for the window release CI to pass : https://github.com/Doublonmousse/rnote/actions/runs/29529431184 (and to double check we do get the cli.exe)

looks good now 👍 Tested the artifact and confirmed the CLI is bundled and added to PATH on installation.
