add Hooks _afterTokenTransfer for ERC1155

Added Hooks of _afterTokenTransfer for ERC1155

Just like ERC721, add the hooks of _afterTokenTransfer for ERC1155.

Currently ERC1155 only have the before Hook, no after hook, hope to add this.

Example

Source Code: https://polygonscan.com/address/0x2048c74851f2ed5c45db70ccb7898a73cfede11e#code#L1343

Merge2048 is ERC-1155, but any address can't hold the same token id.

When the to address receives a token, which to address already had the same id, it'll be merged to the next.

In this case, we need the _afterTokenTransfer to handle it.

Thank you @CryptoV8 for this proposal

I guess this does make sense for simmetry with the other token standards, would you agree @Amxx?

As it is now there is unnecesary memory overhead by invoking _asSingletonArray once for before and once for after, the array can be reused instead.

I'm not able to build on top of this branch, I've added commits and pushed that to my repo:

@Amxx It's because @CryptoV8 created this PR from their master branch. You can open a new PR to supercede this one.
