dev-games/godot: remove slotting support and USE=runner

Mostly to be easier to maintain, see also bug #938658.

Few notes:
- use SLOT=0 to avoid looking inconsistent when godot5 exists
- not doing slotmove given if a package in an overlay (none
  in-tree) depended on godot:4 and has a game invoke godot
  with "4" it'll be broken with this version
- no !blocker given all this does is drop the 4 suffix, so
  no files conflict (essentially a new slot, except the old
  ones were dropped), users that didn't want a specific slot
  and using .desktop to start it won't notice a thing after
  depclean the old
- USE=runner was intended for packaging games with system godot
  but that never really been used and games would be break too
  frequently even if we did without doing major.minor slots
  (dropping it also allows to build faster), could revisit if
  we really want this possibly with a separate godot-runner
  slotted package (aka a simplified build without much work to
  adapt to slots)
