remote: Add API to allow for persistence on RemoteDesktop sessions

[whot]

Same as the ScreenCast API

Fixes #127

Marking as Draft until I've sold off the right to rename this to a more sensible function name to the highest bidder. Any suggestions?

libportal is not API nor ABI stable, so I'd be okay with breaking API for the next stable release.

For now, I guess a _full variant of this function should be enough

Has that been the case always? If that's the case, how can libportal be suitable for any application that intends to be both distributable via Flatpak and traditional distributions?

That's how I've been approaching libportal development since at least 2021 🙂

Personally, I consider libportal suitable for Flatpak applications only... somewhat like a Rust / cargo dependency, you have to pinpoint the exact version you want in the manifest.

Renamed to _full and tests updated and one extra new test added, should be ready.

That is not what I would have assumed. Anyway, filed #129.
