Load rune bases from all non-RACE runes, dropping static_rune_runebase reads

The 315 static_rune_runebase rows are exactly the non-RACE runes, so the loader
selects by rune_type. Removes the server type/subtype columns (no live reader),
the runereq/overwrite path, the GET_RUNEBASE cache-miss query, the runebase
attribute handler, the racerune/baseclassrune loaders and the 111111 checks.
No value changes.
