Converting third-party applets for Wayland

[fossfreedom]

This issue is to track those third-party applets we currently package in backports

At a minimum for the first offering we will need to have stub packages in the wayland PPA to prevent v1 vs v2 issues

Where we don't actively maintain these ourselves, lets offer the maintainer a PR to resolve - often a meson option or similar to allow compilation against v1 vs v2.

• budgie-analogue-clock-applet - packaged for wayland PPA
• budgie-browser-profile-launcher - uses popover.resize and popover.set_default_size that need replacing (worked fine when switched to using set_size_request)
• budgie-calendar-applet - Tested working
• budgie-carbon-tray-applet  - This is unlikely since xembed to X specific. so lets just stub this package
• budgie-clipboard-applet  - Tested working
• budgie-cpufreq-applet - Tested working - we'll need to patch ourselves since their is no longer a working upstream
• budgie-cputemp-applet - Tested working
• budgie-lightpad-applet - this covers both the applet and the main lightpad app. - Main app v0.8 does not work, applet itself does work
• budgie-media-player-applet - Tested working
• budgie-performance-gauge-applet - Tested working
• budgie-pixel-saver-applet - doubtful since I think this I think has X specific bits, but lets test anyway. - Tested but does not work (uses wnck)
• budgie-sys-monitor-applet - Tested working - we'll need to patch ourselves since their is no longer a working upstream
• budgie-user-indicator-redux-applet - Tested working

looking at lightpad (main app)

not working as-is:

Main app in git still uses code known not to work under Wayland. i.e.

Browser profile launcher applet uses popover.resize and popover.set_default_size, which would need to be replaced to be functional, but will work otherwise
