parser: separate actions for primary expression and prefix operator

This will allow us to define both a primary expression, ":", and a prefix
operator, ":y". The ambiguity will be resolved by the next patch.

Prefix actions in elements table are adjusted as follows:

  original prefix      primary  prefix
  -----------------    -------- -----------------
  ("group", 1, ")") -> n/a      ("group", 1, ")")
  ("negate", 19)    -> n/a      ("negate", 19)
  ("symbol",)       -> "symbol" n/a
