[Bleeding] Use proper teleport reason for /tp command. Fixes BUKKIT-5348

Previously, when calling the /tp command with coordinates, no TeleportCause
was passed, causing the resulting PlayerTeleportEvent to be called with
TeleportCause.PLUGIN instead of TeleportCause.COMMAND. This commit adds the
missing TeleportCause to ensure that the resulting PlayerTeleportEvent
reports the correct TeleportCause.
[Bleeding] Add SpawnReasons to cover new Minecraft features.

Adds BUKKIT-5370, BUKKIT-5378, BUKKIT-5382, BUKKIT-5482. Covers zombie
villagers, ocelot babies, silverfish popping out of blocks, and mobs
spawning with a mount.
[Bleeding] Add new TargetReasons to EntityTargetEvent.

This commit adds three new TargetReasons to EntityTargetEvent to address
missing cases where the event is not currently fired.

The first, TargetReason.TARGET_ATTACKED_NEARBY_ENTITY, is used when a
neutral wolf is attacked, causing all nearby wolves to turn hostile and
attack the first wolf's target.

The second, TargetReason.REINFORCEMENT_TARGET, is used when a zombie summons
reinforcements and the new zombie targets the first zombie's target.

The third, TargetReason.COLLISION, is used when an iron golem collides with
a hostile entity, causing it to begin targeting the entity it collided with.
Add BlockMultiPlaceEvent. Adds BUKKIT-5558

Some blocks, such as beds, doors, or flowers, are actually composed of
multiple blocks when they are placed.  Currently, to detect how many
blocks are actually modified a plugin has to perform various calculations
to determine the directions of relative blocks, many of which are
difficult to perform and can easily return false positives.

This commit adds in a BlockMultiPlaceEvent, which adds in easy support for
accessing all blocks modified by the placement of a block.
