Remove durationKind options in math methods

We decided in 2020-07-31 Champions' meeting to simplify this type by removing the ability to choose a particular duration kind. Instead, developers who want to use non-hybrid durations can convert to DateTime or Absolute and perform the math there. * Remove `durationKind`-related TS types * Remove `durationKind` options from `plus`, `minus`, and `difference`. * Remove `calculation` option from `compare` * Remove disambiguation from math methods, because hybrid durations use `compatible` disambiguation per RFC5545. * Simplify math implementation considerably!
