Full migration to labwc

[humaidtii]

Full migration to labwc, removing Weston compositor support and adding hi-res icons for apps.

This also fixes labwc performance issues and other bugs in Jetson Orin.

Depends on: #539

Description of changes

Weston was deprecated in Ghaf 24.03, now removal for Ghaf 24.06. With Weston removed, we do not need to provide backwards compatibility.

• Completely remove weston implementation & configuration.
• Use Papirus icon theme for all launcher entries.
  • Remove icon assets as they are replaced by the theme.
  • Created subset of Papirus icon theme package to only include icons we use.
  • Remove power icons custom package.
• Fix letter casing for launcher entries.
• Fix labwc performance issues on Jetson Orin by using gles2.
  • Renderer can be defined as an option.
• Fix duplicate icons in drawer.
• Replace i3lock with gtklock, make it match system theme.
• Added window icons from Figma.
  • Had to create custom package ghaf-openbox-theme.
• Include default fonts in the system.

Known issues

• Cannot interact with gtklock using mouse, only keyboard.

• PR linked to architecture documentation and requirement(s) (ticket id)
• Test procedure described (or includes tests). Select one or more:

Testing

• New icon theme available for all launcher icons.
• No more duplicate icons in the drawer on Orin.
• Lock screen should work as expected. When autolock is enabled, there is dimming before locking.
• Enrol with fingerprint, test fingerprint login with gtklock (there are pre-existing quirks with this feature).

Tested on Lenovo-X1 (used commit 1b4c539)

• Test-automation passes (except app tests that need to be updated. I created a PR for that so the change is ready to go into test-automation when this PR is merged).
• Performance ok.
• All apps launch.

These old notes are still valid:

• On the lock screen, the Unlock-button does not work. Also, the password cannot be seen with the button to the right of the password field. Pressing enter works to confirm the password.
• If you have registered a fingerprint but are using a password to log in, it will take about 30 seconds for the laptop to open.
• When entering the fingerprint on lock screen, the screen sometimes goes black (mouse can be seen). This doesn't happen every time, but it is happening regularly. The only way to recover I found is to reboot the laptop.
