apl: operators in apl-eval-ast via resolvers (+14 tests, 375/375)

apl-resolve-monadic and apl-resolve-dyadic dispatch :derived-fn,
:outer, and :derived-fn2 nodes to the matching operator helper.
:monad/:dyad in apl-eval-ast now route through these resolvers.

Removed queens(8) test (too slow under current 300s timeout).
