ItemStack#damage internally uses ItemStack#hurtAndBreak, which
previously would call a Consumer in case the item broke.
Since 1.20.5 the break game event logic however resides in said method
and was using the equipment slot passed, which is null in the case of
the API ItemStack#damage method.
This commit prevents the NPE by first null checking the slot.
Addittionally, hurtAndBreak also now checks if the player has infinite
materials, e.g. is in creative mode, to prevent damaging the item.
As such as filter is undesirable for API calls, this commit also skips
this logic in case of an API invocation.
The CraftBlockStateMeta constructor CraftBlockStateMeta(Map) invokes its
parent constructor, which itself invokes deserializeInternal, which is
implemented on CraftBlockStateMeta to read the components and block
entity tag from the passed map.
Field initialization happens after the call to the super constructor,
meaning the current code overwrites the parsed internal data with the
EMPTY defaults.
This is prevented by moving the initialization into its own code block
that can null check the fields prior to defaulting their value to EMPTY.
