games/veloren-weekly: split CLI into subpackage

[jbeich]

Summary

Due to missing USE_*.<subpkg> helper and for POLA sake I've moved out CLI to help headless users. Turning main subpackage into meta-package to pull both cli and (in future) gui subpackages may be of dubious benefit.

Similar to D43581 except for data subpackage.

Test Plan

$ poudriere testport -j 132i386 games/veloren-weekly~cli

Doesn't seem to work:

$ pkg install veloren-weekly
$ pkg info -x veloren
veloren-weekly-s20240119_1

• Rename common to data subpackage for clarity (game data is used by both CLI and GUI)

• data (aka common before the rename) can be merged into cli subpackage but then main needs to depend on cli
• converting data into a slave port spikes maintenance overhead beyond even flavors with separate builds
