Fix PIE not being cancelled after a cancelled PIEE

[sovdeeth]

Problem

When a user clicks on an entity with a wind charge, for instance, a PlayerInteractEntityEvent is called. Skript uses this to trigger EvtClick, and can properly cancel it. However, then a PlayerInteractEvent is called, Skript skips it to avoid duplicating click events, and doesn't properly forward the cancellation from the prior PIEE.

When determining whether a received PIE should be treated as cancelled, Skript would treat any DENY as a cancellation, except if the click is on AIR and the useItemInHand is NOT DENY. This didn't handle cases like RIGHT_CLICK_BLOCK + DENY useInteractedBlock + DEFAULT useItemInHand. Skript would assume it is cancelled, not handle it, and then the user would shoot a wind charge.

Solution

Forwards the cancellation from PIEE to PIE, and properly tracks PIEE cancellations.
Determines cancellation properly for all PIE combinations. RIGHT_CLICK_BLOCK is complex and not possible to always determine, so I erred on the side of caution and treated it as cancelled ONLY if both uses are DENY. This means a hoe-ing of dirt that was denied solely on one or the other will be treated as uncancelled, despite it clearly being cancelled. There's no good way to solve this without introducing specific syntax to cancel item use or block use (which I will make a feature pr for), but I think this is acceptable for a bug fix.

Testing Completed

Manual confirmation.
