  1. Add HTLCHandlingFailed event 

    Adds a HTLCHandlingFailed that expresses failure by our node to process
a specific HTLC. A HTLCDestination enum is defined to express the
possible cases that causes the handling to fail.

  2. Add utils to handle HTLC handling failure reason 

    We add `HTLCHandlingFailedConditions` to express the failure parameters,
that will be enforced by a new macro, `expect_pending_htlcs_forwardable_conditions`.
