Rework raid self/group frame visibility and rename the solo option

- selfinraid now gates on `not IsInGroup()`, so "show self in raid frames"
  applies only when truly solo (both party and raid suppress it), matching
  the option's actual behavior.
- Hide the redundant group frames when a party is promoted to the raid grid
  (raidforgroup + hide_in_raid), not just in an actual raid. A shared
  hide_group local drives both the party-member and self branches; the
  party-member branch is scoped to cache_raid == 0 so the raidforgroup-mapped
  raid frames (which themselves carry label "party") aren't hidden too.
- Rename "Always Show Self In Raid Frames" to "Show Self In Raid Frames When
  Solo" in gui.lua and all locale files; the four previously-translated
  strings are reset to nil stubs since the meaning changed.
