dev-games/godot: add 4.0_alpha14 (slot:4), unkeyworded

This entered feature freeze on August 3 and "shouldn't" introduce
more breaking changes. Albeit has many known bugs/oddities to be
resolved, and --convert-3to4 hasn't been faring so well (new
projects should probably start on 4 at this point though).

Adding for testing, may look at keywording the first beta which
been planned for early September (devs that need godot:3 may
want to add the slot to their world file now).

Bug: https://bugs.gentoo.org/532730
