Fix review - removes all NFT related code

[FlacoJones]

Removes the following methods from AtomicBountyV1.sol:

• receiveNft

Removes the following storage variables from BountyStorageCore.sol:

• nftDepositLimit
• isNFT

Removes the following methods from BountyCore.sol:

• claimNft
• _receiveNft
• getNftDeposits

Removes the following methods from TieredBountyCore.sol:

• receiveNft

Removes the following methods from DepositManagerV1.sol:

• fundBountyNFT

• Modifies the ClaimManagerV1::claimBounty and ClaimManagerV1::permissionedClaimTieredBounty to remove the logic that looped over NFT deposits

• Removes ERC721Receiver.sol import in BountyStorageCore.sol

Removes if/else logic in BountyCore that used to check whether or not the funding is with an NFT

• updates all tests to remove nft related tests

• updates deploy scripts to deploy without MockNFT.sol

NOTE: I keep the tokenId parameter in bounty funding, and also keep the NFT related events though there is no way no to emit them. This is because we don't want to have to make backwards incompatible changes to the current ABIs used across many services

Changes look good. Removes all logic from bounties. Seems to have gotten all related code. Will keep my out for any that was missed on when checking the rest of the PRs
